evaporation is strongly reduced at low energy we have to admit that we do not have yet a complete description evaluating the emission widths $\Gamma_{\nu}$ at low temperature since one can seriously question the validity of the Weisskopf’s theory at such energies and since our development of the more microscopic phase-space distribution function approach is not complete. Nevertheless in order to investigate particle evaporation, we consider in this section the compound nucleus $^{227}$Pa at a higher total excitation energy of $56$ MeV for which we believe that the Weisskopf’s approach should be approximately valid.\
