Nuclear structure of Pm153 studied with the (t→, α) reaction

The Sm154(t→, α) Pm153 reaction has been studied using a 17 MeV beam of polarized tritons from the tandem Van de Graaff accelerator at the Los Alamos Scientific Laboratory. The α spectra were recorded using a quadrupole-dipole-dipole-dipole magnetic spectrometer with a position-sensitive helical-cathode detector on the focal plane. Spectra were obtained to excitation energies > 2 MeV with a resolution of ∼ 17 keV. It was possible to assign …
