Abstract

In order to investigate the effects of varying angular momentum on the decay of compound nuclei, the compound nucleus 68Ge was produced by bombardment with 4He, 12C and 16O ions. To detect any direct interaction component in the reaction mechanism, recoiling product-nucleus ranges were measured in the 4He case. With the exception of bombardments at energies above 30 MeV in the (α, pn) reaction, it may be concluded that the (α, p), (α, n), (α, 2n) and (α, pn) reactions proceed predominantly via a compound nucleus mechanism. Comparisons of the alpha-induced and 12C induced excitation functions are discussed in terms of angular momentum effects.
