Shell effects in Pb(p,xn) preequilibrium neutron emission

Journal Article · · Phys. Rev. C; (United States)
The /sup 204/, 206, 207, 208Pb(p,xn) reactions have been investigated at E/sub p/ = 25.5 MeV. The hard energy spectra and the structures observed in the preequilibrium continuum are attributed to the nearby double shell closure. Application of semiclassical preequilibrium models requires the reduction of the state density g and/or the use of (1p)(1n)/sup -1/ state densities based on realistic single particle level schemes.
