Application of the J-matrix method to multichannel scattering
- 65 Downloads
In this contribution we describe the multichannel extension to the nonrelativistic J-matrix method, and present differential cross sections for scattering of slow electrons from Argon atoms. Nonrelativistic phase shifts, then the S-matrix and the cross sections have been calculated using newly developed Fortran code, JMATRIX-MULTI. We applied the model Hartree-Fock potential as the scattering potential, which was truncated in the oscillatory basis functions.
