Cross Sections of the 148Sm(n, α)145Nd Reaction in the 4.8–5.3 MeV Neutron Energy Region

Speaker

Igor Chuprakov (JINR)

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.
