Abstract

Excitation functions of alpha-particle induced reactions on ^natNd up to 50 MeV were measured at the RIKEN AVF cyclotron. To derive cross sections activation method, stacked target technique and gamma-ray spectrometry were adopted. Formations of ^153,145Sm, ^{151,150,149,148m,148g,144,143}Pm, and ^149,147Nd were investigated. The results were compared with the previous experimental data and the TENDL-2019 data. Discrepancies among most of them were found.
