Experimental studies and nuclear model calculations on (p, xn) and (p, pxn) reactions on ⁸⁵Rb from their thresholds up to 100 MeV

Excitation functions were measured by the stacked-foil technique for
the reactions ⁸⁵Rb(p, pxn)^{84m, g,83, 82m, 81}Rb 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 pairs ^{85m, g}Sr and ^{84m, g}Rb are discussed qualitatively in terms of the spins of the states involved and the increasing projectile energy.
