Direct neutron decay of analog resonances in /sup 118//sup ,//sup 120/Sb and the structure of the levels of /sup 117//sup ,//sup 119/Sb
Spectra of ..gamma.. rays from the reaction /sup 117/Sn(p, n..gamma..)/sup 117/Sb have been measured in an electrostatic accelerator in the region of the analog resonance with E/sub R/ = 4.491 MeV, J/sup ..pi../ = 0/sup +/, and GAMMA = 32 keV. The partial cross sections are analyzed in the resonance and outside it, the partial widths of direct neutron decay are determined, and the spectroscopic characteristics of the levels of the final nucleus /sup 117/Sb (the energies of the levels, J/sup ..pi../, and the ..gamma..-decay branching ratio) have been obtained more accurately. A similar analysis has been carried out also on the basis of published data for the reaction /sup 119/Sn(p,n)/sup 119/Sb with inclusion of new information on the /sup 119/Sb levels. The structure of the /sup 117//sup ,//sup 119/Sb levels which are intensely populated in direct neutron decay of 0/sup +/ analog resonances is discussed.
