Deeply inelastic scattering ofKr84fromPb208

Abstract

We report here energy spectra and angular distributions for deeply inelastic scattering of $^{84}\mathrm{Kr}$ from $^{208}\mathrm{Pb}$ at laboratory energies of 494, 510, and 718 MeV. The deeply inelastic process is found to be the dominant reaction process at all energies investigated. At the highest bombarding energy the most probable kinetic energy of the deeply inelastic component becomes progressively larger as the grazing angle is approached, in contrast to near barrier energies where the most probable kinetic energy remains more nearly independent of angle. A semiclassical calculation of the deeply inelastic angular distributions, employing the deflection functions calculated from an optical model potential that reproduced the elastic scattering in this system, is shown to reproduce the deeply inelastic scattering at the lower energies.NUCLEAR REACTIONS $^{208}\mathrm{Pb}(^{84}\mathrm{Kr},X)$, $E=494, 510, \mathrm{and} 718$ MeV; measured energy spectra and $\ensuremath{\sigma}(\ensuremath{\theta})$ for quasielastic and deeply inelastic reaction products.
