Inner-Shell Photodetachment of Na− Using R-Matrix Methods

Inner-shell photodetachment of Na− near the L-edge threshold was investigated using the R-matrix method. Significant structure was found in the cross section, and this structure is shown to be related to the complicated correlated electron dynamics endemic in negative ions. Comparison with experiment suggests that the absolute values of the measured cross section might be too small by a factor of two.
