Structural effects in the nuclide distributions of the residues of highly excited systems

Abstract : New data from GSI on the production-cross-section for fragmentation of the systems Fe-56+p and Xe-136+p at 1 A GeV revealed the appearance of even-odd staggering in the cross-section distribution for chains of isotopes with given N-Z. The staggering is strongly enhanced for the chain N=Z, it reduces as the production moves away from the N=Z chain, and it reverses for the most neutron-rich odd-A residues. These phenomena, observed in the residues of rather violent reactions, are related to structural effects in the level-densities below the particle-emission threshold.
