Light charged particle evaporation from hot {31}^P nucleus at E^* ~ 60 MeV

The energy spectra of evaporated light charged particles (LCP) $\alpha$, p, d and t have been measured in $7^$Li(47 MeV) + ${24}^$Mg and ${19}^$F(96 MeV)+ ${12}^$C reactions. Both the systems populate the same compound nucleus ${31}^$F at excitation energy E$^*$ ~ 60 MeV. It has been observed that the light particle spectra obtained in Li + Mg reaction follow standard statistical model prediction, whereas a deformed configuration of the compound nucleus is needed to explain the LCP spectra for F + C reaction, which has been attributed to the effect of larger input angular momentum in the case of ${19}^$F(96 MeV)+ ${12}^$C system.
