Eleven excitation functions for alpha-induced reactions on Zn/sup 64/ were messured up to incident energies of 41 Mev. The values of sigma ( alpha ,p)/ sigma ( alpha ,n) and sigma ( alpha ,pn)/ sigma ( alpha ,2n) in the region of maximum yield were found to be 1.7 and 9, respectively. Reactions involving alpha-particle emission account for about 20% of the total inelastic cross section at 40 Mev. The total inelastic cross section was found to agree with calculated values for r/sub 0/ = 1.6 x 10/sup -13// cm. The competition between different reactions was analyzed in terms of the statistical theory by use of a level density expression of the form W(E) = C exp {2STAa(E- delta )! /sup 1/2}. Values of a ranging from 0.8 to 2.8 were required to fit the experimental results, indicating that the statistical theory is not completely applicable. (auth)
