Description
Cross sections for the 148Sm(n,α)145Nd reaction were measured at neutron energies of 4.8, 5.1, and 6.3 MeV, performed at the EG-5 Van de Graaff accelerator at the Frank Laboratory of Neutron Physics, Joint Institute for Nuclear Research. A double-section gridded ionization chamber was employed to detect the emitted alpha particles. Samples of 148Sm2O3 were positioned back-to-back on the common cathode plate of the chamber. Monoenergetic neutrons were produced via the D(d,n)3He reaction in a deuterium gas target. The neutron flux was monitored with a 3He long counter, and the absolute flux was determined using a 238U3O8 sample. The experimental results are compared with evaluated data and calculations from the TALYS-1.96 nuclear reaction code.
