Description
The light charged particle evaporation from the compound nucleus and
from the complex fragments in the reactions 32S+100Mo, 121Sb+27Al, 40Ar+
164Dy, and 40Ar+natAg is studied within the dinuclear system model. The
possibility to distinguish the reaction products from different reaction mechanisms
is discussed.
From the comparison of the calculated light charged particle (LCP) multiplicities
and experimental data, we show the possible overlap of the decay
products from different reaction mechanisms. With increasing the bombarding
energy the ratio of the LCP multiplicity from the fission-like fragments
to the LCP multiplicity from the compound nucleus increases due to the
increase of fission and quasifission probabilities. The simultaneous description
of the LCP multiplicities and of the production cross sections of the
evaporation residues and complex fragments gives us a chance to distinguish
the reaction products from different reaction mechanisms. The calculated
LCP multiplicities show weak dependence on the reasonable variation of the
level density parameter, and stronger dependence on the Coulomb barrier
heights.
