Time delay in negative ion photodetachment

Time delay in photodetachment has been investigated for few negative ions, Cl-, Br-, I-, and Li-. Very few studies on photodetachment time delay for negative ions are present till date and have been reviewed briefly in the present article. Different many body formalisms, like RRPA, RRPA-R and RMCTD,...

Summary:Time delay in photodetachment has been investigated for few negative ions, Cl-, Br-, I-, and Li-. Very few studies on photodetachment time delay for negative ions are present till date and have been reviewed briefly in the present article. Different many body formalisms, like RRPA, RRPA-R and RMCTD, have been employed to obtain new results on photodetachment time delay, accounting for important electron correlations present in the negative ions studied here. Results on time delay show significant angle dependence near the threshold region, at shape resonance and at Cooper minimum region.
