Abstract

There are very few experimental works on the measurement of angular distributions in the (n, γ) reaction near low-lying p-wave resonances of nuclei. Experiments on the determination of the partial neutron widths on 113Cd and 117Sn nuclei were carried out at Frank Laboratory of Neutron Physics, JINR Dubna in the 1990s. In the capture process of resonant neutrons angular distributions and contribution of p-wave amplitudes into interference were analyzed. Our work presents the results of the study of low-lying p-wave resonances in the (n, γ) reaction on 93Nb nucleus, obtained at the pulsed neutron source IREN from FLNP.
