Even-odd effects in Z and N distributions of light fragments emitted at forward angles in nuclear collisions Ca-40 + Ca-40, Ca-40 + Ca-48, and Ca-48 + Ca-48 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.

Abstract
Even-odd effects in Z and N distributions of light fragments emitted at forward angles in nuclear collisions Ca-40 + Ca-40, Ca-40 + Ca-48, and Ca-48 + Ca-48 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. KeywordsFile in questo prodotto:
