Experimental studies and nuclear model calculations on (p,xn) and (p,pxn) reactions on85Rb from their thresholds up to 100 MeV

Abstract

SummaryExcitation functions were measured by the stacked-foil technique for the reactions85Rb(p,pxn)84m, g,83, 82m, 81Rb from their thresholds up to 100 MeV. Nuclear model calculations were performed using the code ALICE-IPPE both on (p,xn) reactions reported earlier and (p,pxn) reactions described here. The experimental excitation curves and the results of nuclear model calculations were found to be qualitatively in agreement. With the exception of the (p,n) reaction above 40 MeV, the theory appears to reproduce all the experimental data within deviations of about 50 %. The cross section ratios for the isomeric pairs85m,gSr and84m,gRb are discussed qualitatively in terms of the spins of the states involved and the increasing projectile energy.
