Nuclear Lifetimes near1017s from X-Ray Spectrum in Inelastic Proton Scattering onSn112

Abstract
A particle x-ray coincidence experiment for the compound nuclear reaction Sn112(p,p) at 12 and 10 MeV proton energy is presented. A mean nuclear lifetime of 3.4×1017 s for Sb113 at 15 MeV excitation, and of 4.0×1017 s at 13 MeV is deduced.
