Excitation and decay of analogs of excited states of /sup 119/Sn

Journal Article · · Phys. Rev., C; (United States)
; ; ;
The (p,n') reaction to excited isobaric analog states of /sup 119/Sn has been observed using a neutron-proton (n-p) coincidence technique. The n-p coincidence was essential to reduce the neutron background due to population of the t/sub less-than/ states. The states preferentially excited are analogs of the 0.920, 0.921, 1.090, and 1.354 MeV states of /sup 119/Sn which contain the strength of the 2/sup +/ core excitation. These states are observed to decay overwhelmingly to the first-excited (2/sup +/) state of /sup 118/Sn. A value for the overall relative proton decay probability was calculted in order to compare the data with predictions of a two-step model of the (p,n') reaction. Good agreement with the data was obtained, provided that the imaginary part of the neutron optical potential was reduced by the same factor which previously was found necessary to fit quasi-elastic scattering data.
