Sub-Coulomb proton absorption for isotopes of zirconium and molybdenum

Total (p,n) cross sections were measured with enriched targets of /sup 92,94/Zr and /sup 94,95,96,98/Mo, from each threshold energy to approx.6.7 MeV. Proton strength functions were deduced and compared with those of neighboring nuclei. The strength functions were characterized by a minimum which wa...

Zusammenfassung:	Total (p,n) cross sections were measured with enriched targets of /sup 92,94/Zr and /sup 94,95,96,98/Mo, from each threshold energy to approx.6.7 MeV. Proton strength functions were deduced and compared with those of neighboring nuclei. The strength functions were characterized by a minimum which was interpreted as a valley between the 3s and 3p single-particle resonances. Optical-model calculations were performed to fit the deduced strength functions. Systematic variations in the depths of the absorptive potentials were found as a function of mass in the manner suggested by Johnson et al.
