Abstract

Even-odd effects in Z and N distributions of light fragments emitted at forward angles in nuclear collisions 40Ca + 40Ca, 40Ca + 48Ca, and 48Ca + 48Ca at 25 MeV/nucleon and identified in charge and mass with the Chimera multidetector have been analyzed. The amplitude of even-odd staggering effects seems to be related to the neutron to proton ratio N/Z of the entrance channels. A qualitative explanation of this effect, taking into account the deexcitation phase of primary excited fragments, is discussed.
