Evaporation residue cross sections in complete fusion reactions between52Cr-56Fe,63Cu-Ni and63Cu-Ag

Abstract

Evaporation residue cross sections have been measured by the technique of the telescopeΔE ·E counter at very small angles. The angular distribution has been followed down to 2°15′, and rather precise values were obtained for that fraction of the compound nucleus decay after complete fusion for the systems63Cu+Ni,63Cu+Ag and52Cr+56Fe at two bombarding energies. A comparison has been done with evaporation calculations using the code ALICE, and the rotating liquid drop concept. It is shown that a large discrepancy occurs at low energy for these heavy projectiles. The origin of this difference is discussed.
