Investigation of low energy electron collision with

D Geetha, Kalyan Chakrabarti, Dhanoj Gupta2026年6月Plasma Physics and Controlled FusionIF 2.2出版社

A detailed study of electron-impact collision on is presented using the R-matrix method. A high-quality wave function for the target molecule is used at the configuration interaction level to compute the target properties. The R-matrix method is then used to calculate differential, integral elastic, momentum transfer, and electronic excitation cross sections up to 15 eV. The excitation cross sections are calculated from the ground state to the first three electronic excited states of . To check the convergence of the results, the calculations are performed by including eight, sixteen and twenty-four states in the calculations. The total ionization cross section is calculated using the binary encounter Bethe method and presented. Also, the rate coefficient are calculated using Maxwell–Boltzmann distribution. These data will support investigations of edge plasma properties in tokamaks employing boronization for wall conditioning.
