| Abstract: | Cross-sections for production of evaporation residues from the compound nucleus96Ru* formed by fusion reactions28Si+68Zn,32S+64Ni,37Cl+59Co and45Sc+51V have been obtained from the yields of their characteristicγ-rays. The measurements span an excitation energy range of 55 MeV to 70 MeV of the compound nucleus. The evaporation residue
(ER) cross-sections have been analysed in terms of statistical model for the decay of the compound nucleus. A good agreement
is found between statistical model calculation and the experimental evaporation residue cross-sections in all the four cases.
It is shown that the average angular momentum
of the compound nucleus can be deduced from a comparison of the experimentally measured and the statistical model predictions
for the ER cross-sections. The validity of this method of deriving
has been discussed for the case of16O+154Sm system. |
