摘要：
A new improved study of resonance features has been made in the photodetachment process from such strong correlated system as negative ions with np(3) half-filled shells. The photodetachment cross sections from two outer shells of Si-, Ge- and Sn- negative ions have been calculated with account of many electron correlations. The formation and autodetachment of the quasi-bound "nsnp(4)" states revealed themselves as a very sensitive interference structure in the cross section.
