POREĐENJE SETOVA PRESEKA IZ BAZA QUANTEMOL I MORGAN LXCAT I KOEFICIJENATA BRZINE ZA PROCESE RASEJANJA ELEKTRONA NA NEUTRALIMA: HELIJUM I VODENA PARA

Abstract

The present work compares cross section sets for electron scattering from ground state helium and ground state water molecule, which are available at LXCat Morgan database and the new Quantemol-DB. These cross section sets are  used as an input for numerical solving of Boltzmann equation by using electron Boltzmann solver BOLSIG+, in order to obtain transport coefficients, electron energy distribution function and rate coefficients for electron impact scattering processes. The calculated quantities are compared to examine the quality and completeness of the cross section sets provided by Quantemol database for modeling low-temperature plasmas and interpretation of experimental results.This article has been corrected.

Ovi setovi preseka su iskorišćeni kao ulazni parametri za numeričko rešavanje Bolcmanove jednačine primenom Bolcman-solvera BOLSIG+, u cilju određivanja transportnih koeficijenata, funkcije raspodele elektrona po energiji i koeficijenata brzine za procese rasejanja elektrona. Izvršeno je poređenje izračunatih koeficijenata u cilju ispitivanja kvaliteta i kompletnosti seta preseka dostupnih u bazi Quantemol za potrebe modelovanja niskotemperaturnih plazmi i interpretacije eksperimentalnih rezultata
