The temperature of a compound nucleus should decrease for the higher values of its spin angular momentum and so the spectra of the heavier evaporation fragments emitted from the compound nucleus should have progressively steeper slopes. To test this idea, we formed the same compound nucleus ¹⁰⁵Ag at the same excitation energy (E_X=76 MeV) and with very similar spin distribution by ¹⁶O+⁸⁹Y and ¹²C+⁹³Nb reactions and studied back-angle alpha to carbon particle emissions. The compound nucleus character of the reaction was established from the angular distribution of the emitted fragments and the lack of any entrance channel dependence of the angle-integrated yields of the fragments. It was found that the temperatures of the ensembles of the residual nuclei as obtained from the slopes of alpha, lithium, boron, carbon spectra remain about 3 MeV in most cases and higher (about 4.2 MeV) for lithium emission, whereas the statistical model codes predict decrease of the corresponding temperatures from 3 MeV (for alpha) to 1.65 MeV (for carbon). The result could not be understood by adjusting the parameters of the statistical models and might imply the effect of the lifetime of the exit channel fragment plus residual dinuclear system.
