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.
