Shell Inhomogeneities of the Single-Particle Level Spectra in the Practical Model of the Gamma-Decay of Neutron Resonance

In this paper we have taken into account shell inhomogeneities of the single-particle level spectra in the practical model of the gamma-decay of neutron resonance developed in Dubna. The obtained data confirm a dependence of breaking thresholds for Cooper pairs on a shape of investigated nuclei - a phenomenon noticed earlier without taking into account the shell inhomogeneity.

Gamma ray production in inelastic scattering of neutrons produced by cosmic muons in $^{56}$Fe

We report on the study of the intensities of several gamma lines emitted after the inelastic scattering of neutrons in $^{56}$Fe. Neutrons were produced by cosmic muons passing the 20t massive iron cube placed at the Earth's surface and used as a passive shield for the HPGe detector. Relative intensities of detected gamma lines are compared with the results collected in the same iron shield by the use of $^{252}$Cf neutrons. Assessment against the published data from neutron scattering experiments at energies up to 14 MeV is also provided.
