The energy level structure of 154Sm from the (n, n′γ) reaction

Gamma rays from levels in 154Sm between 921 and 1817 keV excitation were observed following neutron inelastic scattering at neutron energies ranging from 1.1 to 2.3 MeV. Level positions and decay mode information were obtained. Gamma-ray production cross sections were determined and then used to deduce neutron inelastic cross sections. The results were compared with the predictions of the compound nuclear statistical theory to establish level spins and parities. © 1973.
