Abstract

Excitation curves have been determined from γ-ray yield measurements for heavyion reactions induced by Elab = 12–30 MeV 16O, 18O and 19F ions incident upon thick targets of 9Be, 10B, 11B, 12C and 23Na. The yields of radioactive decay products with half-lives greater than one second were measured; hence a large number of the outgoing reaction channels could be observed. The preponderance of heavy reaction products suggests compound-nucleus formation as the dominant reaction mechanism. Statistical-model calculations with a spin-dependent level density have been performed, in which the nuclear moment of inertia was treated as a parameter. Many of the results can be explained satisfactorily with a nuclear moment of inertia 0.55 to 0.7 of the rigid body value.
