Abstract: Dechanneling processes for electrons based on the solution of Fokker-Planck equation have been studied. The dynamics of particle distribution density in depth of Crystal has been investigated in dependence on both energy and initial scattering distribution of electron beams. The influence of dechanneling process on spectral intensity of channeling radiation for electrons in crystals is investigated.

Abstract: In this article by using OXBASH shell model code the energy levels of Magnesium isotopes 24Mg and 25Mg are calculated. This code which is based on one of the most applicable nuclear models, deals with evaluating energy levels. Applying the program for each isotope using the defined codes, introduces several files which each file contains a set of data. Meanwhile, the ground state of excitation energy evaluated by OXBASH code together with energy levels and also probable places for nucleons’ placements in each energy level. Programs will be reliable only when results meet experimental procedures. A compilation of SD-shell energy levels calculated with the USD Hamiltonian and has been published around 1988. A comparison had been made between our results and the available experimental data to test theoretical shell model description of nuclear structure in Magnesium isotopes. The calculated energy spectrum is in good agreement with the available experimental data.

Abstract: In this paper, the energy levels of Na and Mg isotopes have been calculated. Calculations were carried out in the SD model space with 13 different potentials using the shell model code OXBASH by applying spin-parity of valance nucleons. OXBASH is a computing code for carrying out calculation of nuclear structure based on shell model. We compared calculated energy levels with experimental results and find the best energy and potential for each isotope.

Abstract: Phosphorus (P) has 23 isotopes from 24P to 46P, only one of these isotopes, 31Pis stable; such as this element is considered as a monoisotopic element. The longest-lived radioactive isotopes are 33P with a half-life of 25.34 days and the least stable is 25P with a half-life shorter than 30ns. Almost all of them are high energy beta-emitters which have valuable applications in medicine, industry, and tracer studies. Calculations of energy level properties of the Phosphor isotopic chain with A = 31 (N=15) to 35 (N=20) calculated through shell model calculations using the shell model code OXBASH for Windows. A compilation of sd-shell energy levels calculated with the USD Hamiltonian has been published around 1988.A comparison had been made between our results and the available experimental data and USD energies to test theoretical shell model description of nuclear structure in Phosphor nuclei. The calculated energy spectrum is in good agreement with the available experimental data.
