    Abstract: In this article, the energy levels of Aluminum isotopes 24Al and 25Al are calculated using OXBASH shell model code. The calculations were carried out in the SD model space with the W and CW Hamiltonian [1, 2] using the code OXBASH for windows PC [3]. This code which is based on one of the most applicable nuclear models, the shell model, deals with ... Show More

    Abstract: Polymer materials are required to be used in nuclear power stations as insulation materials of electrical wire and cable. For the use of polymer materials in such regions, the electrical performance under different environments of radiation is different from that without radiation has been found through previous research. The aim of this paper is t... Show More

    Abstract: Using linear least squares method and by data of atomic mass, the present study calculates the coefficients of volume, surface, Coulomb, and asymmetry terms in semi-empirical formula. Our findings show that the mass of neutron and hydrogen can be estimated via developing this example. The results of the present calculations are also compared with t... Show More
