Odd-even staggering effects on charge distributions are investigated for
fragments produced in semiperipheral and central collisions of 112Sn+58Ni at 35
MeV/nucleon. For fragments with Z<16 one observes a clear overproduction of
even charges, which decreases for heavier fragments. In peripheral collisions
staggering effects persist up to Z about 40. For light fragments, staggering
appears to be substantially independent of the centrality of the collisions,
suggesting that it is mainly related to the last few steps in the decay of hot
nuclei.
