nuclear level densities and spin cut-off factors have been deduced for nuclei in the mass region 24‹a‹63,from a microscopic theory, which includes nuclear pairing interaction. single particle levels for both seeger and nilsson potentials were used in the calcdations. level densities extracted from the theory are compared with their conesponding experimental values, it is found that the overall ...

an analysis of selected fission fragment angular distributions from helium-ion induced fission is made using an exact theoretical expression. theoretical anisotropies obtained with the transition state model are compared with their corresponding values deduced from the statistical scission model. the nuclear moment of inertia extracted from the model calculations are compared with their estimat...

A typical form of mass formula is re-explained in terms of nuclear structure. For N ≈ Z nuclei, we propose to start with the shell model picture and to consider the T = 0 2n − 2p (α-like) correlations in the first place, instead of the symmetry energy as a prior concept. Afterward, the symmetry energy is described on the basis of the α-like superfluidity caused by the T = 0 2n − 2p correlations...

Introduction: Proton therapy is a type of radiation treatment that it uses protons to treat cancer. Because of the protons’ unique ability to distribute the radiation dose more directly to the tumor, it minimizes the damage to nearby healthy tissues. The rate of energy loss by the ion in the target is called stopping power. The total stopping power is sum nuclear and electroni...

Although there have been some severe nuclear accidents such as Three Mile Island (USA), Chernobyl (Ukraine) and Fukushima (Japan), nuclear fission energy is still a source of clean energy that can substitute for fossil fuels in a centralized way and in a great amount with commercial availability and economic competitiveness. Since the pressurized water reactor (PWR) is the most widely used nucl...

Objectives-Firstly, to ascertain whether mortality among workers of the former Spanish Nuclear Energy Board (Junta de Energia Nuclear-JEN) was higher than that for the Spanish population overall; and secondly, if this were so, to ascertain whether this difference was associated with exposure to ionising radiation. Methods-A retrospective follow up of a cohort of 5657 workers was carried out for...
