Abstract

Isomer ratios for87Y,86Y and84Rb from α-induced reactions on85Rb in the energy range between 20 and 60 MeV have been measured. The data show a characteristic increase followed by a decrease with the increase in bombarding energy. The fall in the isomer ratio values are explained on the basis of enhanced angular momentum depletion by the precompound particles and thereby leaving the compound system at low angular momentum states. A different reaction mechanism has been proposed for the low yield of the high spin isomer in the /α, αn/ reaction in85Rb.
