Photoionization of the 4s0 Ground State of Atomic Nitrogen and Atomic Nitrogen4s0-4p Oscillator Strengths

摘要

The R-matrix method is used to obtain the cross section for the photoionizationof the ground state of atomic nitrogen together with oscillator strengths for transitions between symmetries 4s0 and 4p. Using these results the discrepancy between theory and experiment for the photoionization cross section near threshold can be resolved. There have been numerous theoretical studies of the photoionization of the ground state of atomic nitrogen but few experimental studies.
