  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.
