Abstract

The results of experimental measurements of (p, α) reactions on nuclei in the rare earth region are reported. It is shown that the dominant acting mechanism is precompound emission. From the absolute cross-section value fitting, the α-preformation probability in the target nucleus can be evaluated. Its values are very close to the ones extracted from (n, α) analysis in the same mass region.

    Citation Excerpt :

    The sharp peak at low energies and steep rise at high energies that can be seen in the TENDL theoretical data is hence questionable and is not reproduced by the experimental values. Only one data point was measured by Milazzo-Coli et al. in 1974 [23] on enriched 154Sm with unknown enrichment rate, which might cause the disagreement (we normalized it assuming 100% enrichment). The radionuclide 150Pm (GS, E(level) = 0.0 keV, Jπ = 1−, T1/2 = 2.68 h, β−: 100%) is a closed nuclei from the point of view of decay of parents.
