EVALUATION OF ABSORPTION CROSS-SECTION FOR THE PHOTOIONIZATION OF ALKALI ATOMS

Abstract

The photoionization cross section of lithium atom for the ground (25) and excited (2p) states have been calculated using the Dipole approximation for the radiation matter interaction. Computer prgramms have been developed and results are presented for the phase shifts, cross sections and the asymmetry parameter. Comparison of the results with other calculation is also presented
