| Abstract: | Summary The neutron capture behavior of certain radioactive rare earth nuclides, among them 171Tm and 151Sm, is of interest for astrophysical reasons and for the interpretation of radiochemical data from underground nuclear tests. In order to measure neutron capture excitation functions for these radionuclides, targets were produced that met stringent requirements. This paper describes the purification chemistry and target preparation methods that were employed in order to deliver appropriate samples for study. |
