Dominance of correlation and relativistic effects on photodetachment time delay well above threshold

Saha, Soumyajit; Deshmukh, Pranawa C.; Kheifets, Anatoli; Manson, S T


Wigner time delay in photodetachment from the 3p3/2 and 3p1/2 subshells of Cl− has been studied in the vicinity of the 2p3/2 and 2p1/2 thresholds, using the relativistic random phase approximation (RRPA). The results show time delay spectra dominated by many-body correlations along with very complicated dependence on the energy over a broad spectral range. In addition, the time delay spectra of the two spin-orbit split 3p subshells differ significantly from one another, thereby revealing the...[Show more]
