The excitation function for the 45Sc(α,αn)44Scm+g reactions have been measured at beam energies from 20 to 90 MeV. These provide a beam monitor for alpha particle induced reaction studies. The excitation functions and isomer ratios are discussed with particular reference to an apparent error in the decay scheme of 44Scm.

A detailed comparative study of the sub-barrier fusion of the two near-by systems 36S+50Ti,51V was performed at the National Laboratories of Legnaro (INFN). Aim of the experiment was the investigation of possible effects of the non-zero spin of the ground state of the 51V nucleus on the sub-barrier excitation function, and in particular on the shape of the barrier distribution. The results sh w that the two measured excitation functions are very similar down to the level of 20 - 30 μb. The same is observed for the two barrier distributions. Coupled-channels calculations have been performed and are in good agreement with the experimental data. This result indicates that the low-lying levels in 51V can be interpreted in the weak-coupling scheme, that is, 51V(I) = 50Ti(2+)⊗ p(1 f7/2).

Good Agreement

Excitation functions have been measured for alpha-particle induced reactions on natural nickel leading to the production of 62 Zn , 61 Cu , 56,57 Ni and 56,58 Co radioisotopes up to 50 MeV by the activation method and gamma-ray spectrometry. Most of these radioisotopes are produced by one or two alpha-particle emissions and a few nucleon emissions. The excitation functions were compared with semi-classical models codes, like ALICE/90, which includes a shell corrected level density formulation and the COMPLET, which takes into account angular momentum removal effects. In the case of multi-nucleon emission channels, ALICE/90 gives fairly good agreement. The COMPLET code on the other hand, explains the α-particle emission channels in a more convincing manner.

The Cross

A prescription for separating the elastic cross section into its coherent and incoherent parts is used to gain more information about the excitation function at 90° and at 180°. Approximations become useless over most of the energy range owing to the extreme sensitivity of the cross section. Despite the apparent smooth energy dependence of the coherent and incoherent parts, interpolation does not generate the observed structure in the excitation functions.
