FEM R-matrix calculations of electron-H{sub 2} collisions
Electron - H{sub 2} collisions have been studied using the finite-element R-matrix method. The author`s approach uses a mixed finite-element and Gaussian basis to describe the continuum electron. In the inner region, the multi-centered nature of the Gaussian basis provides an efficient representation in the regions of space near the nuclei, whereas the piecemeal and energy-independent nature of the FEM basis is particularly well suited for R-matrix calculation. Fixed nuclei calculations have been carried out at 1.4 a{sub o} the equilibrium internuclear distance of the ground state. Up to six target states are included: the X{sup 1}{Sigma}{sub g}{sup +}, b{sup 3}{Sigma}{sub u}{sup +}, a{sup 3}{Sigma}{sub g}{sup +}, B{sup 1}{Sigma}{sub u}{sup +}; c{sup 3}{Pi}{sub u}, and C{sup 1}{Pi}{sub u} states, and configuration-interaction functions are used to described the target states. The results will be compared with available theoretical and experimental data.
