Charged-particle emission in reactions of /sup 90/Zr with 10--86-MeV protons

Journal Article · · Phys. Rev., C; (United States)
;

Excitation functions for 12 nuclear reactions of type /sup 90/Zr((p,(2--4) p, (1--6) n) have been measured for incident proton energies from 10--86 MeV. These complex excitation functions have been decomposed to yield a component due to emission of one or two ..cap alpha.. particles, and a component due to the emission of individual nucleons. Combining the ..cap alpha.. particle portions of the decomposed excitation functions, the excitation energy spectra for those events associated with ..cap alpha.. particle emission have been derived. Having estimated the excitation functions for a few missing reactions, the total probability of emission of seven combinations of charged particles as a function of incident proton energy has been calculated. The implications of the results on the preequilibrium model of nuclear reactions are discussed. (AIP)
