Alpha particle induced reactions in the target elements copper and tantalum were studied. The excitation functions of63Cu(α, n) +65Cu(α, 3n),65Cu(α, 2n),181Ta(α, 2n) and181Ta(α, 4n) were measured up to 75 MeV.Eight new energy point cross-sections were measured for the first time. The experimental results were compared with the predictions of updated hybrid model (ALICE/85/300) as well as with index model using the initial exciton numbern0=4 (4poh) and level density parameter,a=A/8. A general agreement was found for all the reactions with both the models.
