Abstract
-delayed proton emission from nuclides in the neighborhood of Sn was studied at the National Superconducting Cyclotron Laboratory (NSCL). The nuclei were produced by fragmentation of a 120 MeV/nucleon Sn primary beam on a Be target. Beam purification was provided by the A1900 Fragment Separator and the Radio Frequency Fragment Separator. The fragments of interest were identified and their decay was studied with the NSCL Beta Counting System in conjunction with the Segmented Germanium Array. The nuclei Cd, In, In, and In were identified as -delayed proton emitters, with branching ratios , 5.5%, 19(2)%, and 0.9(4)%, respectively. The branching ratios for Ru, Rh, Pd, and Ag were deduced for the first time with , 1.3(5)%, 1.9(1)%, 7.5(5)%, and 2.5(3)%, respectively. The value for Sn was deduced with higher precision than previously reported. The impact of the newly measured values on the composition of the type I x-ray burst ashes was studied.
