A new Nilsson single-particle structure is proposed for neutron-rich nuclei near 132Sn. In general, a large reduction in spin–orbit interaction is required and the neutron N = 82 gap persists in the new set of parameters. The ground state deformations for several isotopic chains are studied with this set and compared with the results of the standard set and with measured ones. Collective bands ...
متن کاملThe effect of source shield on landmine detection
Background: Several landmine detection methods, based on nuclear techniques, have been suggested during the recent years. Neutron energy moderation, neutron-induced gamma emission, neutron and gamma attenuation, and fast neutron backscattering are nuclear-based methods used for landmine detection. The aim of this study is to use backscattered neutron for landmine detection. Materials ...
متن کاملSingle-neutron states in (101)Sn.
The first data on the relative single-particle energies outside the doubly magic (100)Sn nucleus were obtained. A prompt 171.7(6) keV gamma-ray transition was correlated with protons emitted following the beta decay of (101)Sn and is interpreted as the transition between the single-neutron g(7/2) and d(5/2) orbitals in (101)Sn. This observation provides a stringent test of current nuclear struc...
متن کاملStructural Changes of Hot Rotating Neutron Deficient Doubly Magic Nucleus sn
This paper presents results of statistical calculations of single-particle characteristics of nuclei, excitation energies and shape transition in the Sn isotope with neutron number 50, which is the extremely neutron deficient isotope. It is a very rare and unstable isotope which does not occur in nature, but only on the surface of exploding stars for less than a second. The spherical nucleus at...
متن کاملA review on neutron shielding performance of nano-composite materials
Neutron sources employed in different applications in both medicine and industry. Due to the harmful effects of neutron particles on living organisms, radiation shields have played a vital role in radiation protection against neutrons. In recent decade, numerous investigations conducted on the design and fabrication of nanocomposites as more efficient shielding materials against fast and therma...
