Statistical model analysis for the deexcitation ofTe117atE*=71 and 107MeV in the reactionsN14+Rh103andAr40+Se77

A detailed statistical model analysis is presented for the deexcitation of the compound nucleus ${}_{}{}^{117}{}_{}{}^{}\mathrm{Te}$ at excitation energies of 71 and 107 MeV being formed at both energies with large angular momenta by the reactions ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ + ${}_{}{}^{103}{}_{}{}^{}\mathrm{Rh}$ and ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ar}$ + ${}_{}{}^{77}{}_{}{}^{}\mathrm{Se}$. The competition of charged particle ($p,\alpha$), neutron, and $\gamma$ emission is explicitly considered in the calculations for each decay step throughout the whole evaporation cascades. By this method the energy spectra of protons and $\alpha$ particles in the four reactions can be well reproduced with respect to their form, average kinetic energies, and absolute cross sections with a consistent set of the statistical model parameters.
