Complex nuclear-structure phenomena revealed from the nuclide production in fragmentation reactions Original Research Article

Complex structural effects in the nuclide production from the projectile fragmentation of 1A GeV 238U nuclei in a titanium target are reported. The structure seems to be insensitive to the excitation energy induced in the reaction. This is in contrast to the prominent structural features found in nuclear fission and in transfer reactions, which gradually disappear with increasing excitation energy. Using the statistical model of nuclear reactions, relations to structural effects in nuclear binding and in the nuclear level density are demonstrated.
