Biagi (transcription of data from SF Biagi's Fortran code, Magboltz.)click to expand or collapse

PERMLINK: www.lxcat.net/Biagi

DESCRIPTION: These data were transcribed from S.F. Biagi's FORTRAN code, MagBoltz, versions 8.9 and later. The exact version number is given for each species. At this time, the Biagi database contains cross sections for rare gases, for a few simple molecules, and for SF6. The transcription of cross sections for other gases is in progress. These data were compiled for use a Monte Carlo simulation (or multi-term Boltzmann code), but their use in a 2-term Boltzmann solver gives reasonably accurate results in most cases. The the LXCat data tables do not always have the same energy resolution as the original data in the MagBoltz code. This limited energy resolution can introduce small (1%) differences in the calculated drift velocity at low E/N. For history and detailed notes, see http://consult.cern.ch/writeup/magboltz/ Oct 2011 : update of Ar and Kr data taken from MagBoltz version 8.97 Nov 2011 : small changes in Xe ionization cross sections, taken from MagBoltz v8.97 March 2015: cross sections for SF6 were transcribed from Magboltz version 10.6 from February 2014.

HOW TO REFERENCE: Fortran program, MAGBOLTZ, S.F. Biagi. The version number of MAGBOLTZ from which the cross sections were transcribed is provided in the comment for each species. This version number must be included in the reference.

BSR (Quantum-mechanical calculations by O. Zatsarinny and K. Bartschat)click to expand or collapse

PERMLINK: www.lxcat.net/BSR

DESCRIPTION: The results in this database are from non-relativistic (LS-coupling), semi-relativistic (Breit-Pauli), and full-relativistic (Dirac) B-spline R-matrix (close-coupling) treatments of electron collisions with a number of species. Individually optimized, term-dependent sets of non-orthogonal valence orbitals are used to account for the potentially strong term dependence in the one-electron valence orbitals, especially for the heavy noble gases. The predictions have been validated against a number of benchmark experimental data measured in crossed-beam setups. Very good agreement is generally achieved in the near-threshold resonance regime, where the excitation process is often dominated by negative-ion resonances. For e-Ar collisions, angle-differential cross sections are also available. These were obtained in the semi-relativistic framework.

CCC databaseclick to expand or collapse

PERMLINK: www.lxcat.net/CCC

DESCRIPTION: The convergent close-coupling method (CCC) is a non-relativistic formulation of the close coupling equations that solves for the scattering T-matrix in momentum space. The CCC database contains angle-integrated cross sections of electron scattering from atomic hydrogen H [1] and helium He [2] atoms and the molecular hydrogen ion H2+ [3]. For H and He the full set of cross sections (elastic, momentum-transfer, excitation, and ionization cross sections) are available for scattering from the ground state. The angle-differential cross sections and cross sections for scattering from excited states are available on request from the authors. For H2+ the CCC data base provides results from adiabatic-nuclei close-coupling calculations of hot (vibrationally excited) H2+. Collision data of H2+ and its isotopologues was obtained for scattering from each vibrational state of the electronic ground state and for the distribution of vibrational levels weighted according to the Frank-Condon (FC) factors. In the near future the CCC database will add comprehensive collision data of electron scattering from molecular hydrogen H2. Presently the database contains total cross section and cross sections for elastic scattering and ionization in the energy range from 0.1 to 300 eV and differential cross sections at 17.5 eV for the first seven states of H2 [4].

IAA (IAA)click to expand or collapse

PERMLINK: www.lxcat.net/IAA

DESCRIPTION: Combination up to 2022 of experimental, theoretical and own calculations of electron integral/differential cross sections with atmospheric species. The work was realised by Anthony Schmalzried during his PhD thesis at the Instituto de Astrofísica de Andalucía in Granada, Spain under the supervision of Dr. Alejandro Luque and Dr. Nikolai Lehtinen from the University of Bergen, Norway. Compiled data was only extracted from published results but not from other databases on lxcat. Highlights: * Use of analytical formulae for electronic exc. and ionisation. * Use of Born-Bethe extrapolation for total scattering cross section * Use of the scattering length for the CS at zero energies * Complete set of electronic inelastic processes in the mathematical sense of the dipole oscillator strength (it satisfies the Bethe sum rule) * The DCS is coherent with the elastic integral and momentum-transfer cross sections. Vulnerability: All momentum-transfer CS labelled in the datagroup MOMENTUM have been converted from the RESIDUAL elastic cross section through the multiplication by 1- (average deviation cosine). These may not be necessarily accurate, especially in regions where the DCS is sparse. Transport parameters at low energies with this MTCS will be less accurate than in other databases because our MTCS are derived from the residual elastic cross section after subtracting all inelastic (except rotational exc.) from the total scattering cross section (which is usually known with great accuracy). You may wish to take momentum-transfer cross sections from another database, but beware that even if more accurate results are obtained, the database will lose its coherence!

IST-Lisbon databaseclick to expand or collapse

PERMLINK: www.lxcat.net/IST-Lisbon

DESCRIPTION: IST-Lisbon database contains up-to-date electron-neutral scattering cross sections (together with the measured swarm parameters used to validate these data), resulting from the research effort of the Group N-Plasmas Reactive: Modelling and Engineering (N-PRiME) with IPFN/IST (Instituto de Plasmas e Fusao Nuclear / Instituto Superior Tecnico), Lisbon, Portugal.
The data, compiled from the literature, correspond to contributions from different authors (see detailed references in the database). For each gas the database presents a COMPLETE SET of cross sections, validated against measured swarm parameters by solving the two-term homogeneous electron Boltzmann equation. In most cases, predictions are in agreement with measurements within 1-20%, for reduced electric fields E/N ~ 1e-4 - 500 Td. To improve predictions at low E/N, some sets need to be completed with rotational cross sections, also available in the database.

DESCRIPTION: A compilation of atomic and molecular data, assembled and evaluated by A.V. Phelps and collaborators. Please refer to these data using the sources cited for each gas. We make no claims for these cross sections beyond those stated in the papers where they are published or cited. In most cases these cross sections were assembled in the 1970's and 1980's. In only a few cases have they been modified or tested since that time. I do not plan any updates. Additions have been made when cross sections have been assembled for other purposes. Since the JILA information center was closed by NIST, there is no one there to help you. Opinions expressed are those of AV Phelps and do not imply JILA, CU, or NIST approval.

DESCRIPTION: The SIGLO database is the "in-house" data used by the group GREPHE at LAPLACE in Toulouse. The data are taken from different sources as indicated for each gas. Please refer to original sources in publications. An early version of this data file, "siglo.sec", was distributed with BOLSIG. The main changes in the present version are :
The format has been changed to be compatible with BOLSIG+.
Scale factors have been incorporated in the data and no longer appear explicitly.
We have removed the CF4 cross section data because of their limited precision (probably due to digitization errors). For the moment our recommendation is to use the dataset in the Morgan database.
He : The present data are from the compilation of A.V. Phelps (see reference in the Phelps data base).
O2 : We recommend using the data in the Phelps database for this species.
H2 : We recommend using the data in the Phelps database for this species.
Cl2 : The present data are an updated compilation (Jan 2012) by J Gregorio and LC Pitchford.
Cu : Feb 2012. Digitized from Tkachev A N, Fedenev A A and Yakovlenko S I, Laser Phys. vol.17, p. 775 (2007)
Kr : Nov 2012. We re-digitized the data from figs. 1 and 5 in H. Date, Y. Sakai and H. Tagashira, J. Phys. D 22 1478 (1989). With respect to the previous data from this same reference in the SIGLO database, there are some changes in the threshold values and in the magnitudes of the inelastic cross sections.
