Abstract

In the present work, accurate high lying single photoionization resonance energies for Aluminium-like P²⁺ and magnesium-like P³⁺ are reported. Calculations are performed in the framework of the Screening Constant by Unit Nuclear Charge (SCUNC) formalism. The resonance energies and quantum defects obtained compared very well with experimental data of Hernández et al., (2015) along with DARC, Dirac Atomic R-matrix Codes computations of Wang et al., (2016). Analysis of the present results is achieved in the framework of the standard quantum-defect theory and of the SCUNC-procedure based on the calculation of the effective charge. It is demonstrated that the SCUNC-method can be used to assist fruitfully experiments for identifying narrow resonance energies due to overlapping peaks. New precise data for Aluminium-like P²⁺ and magnesium-like P³⁺ ions are presented as useful guidelines for investigators focusing their challenge on the Photoionization of aluminum-like P²⁺ and magnesium-like P³⁺ heavy charged ions in connection with their application in laboratory, astrophysics, and plasma physics. In addition, our predicted data up to n = 30 may be of great importance for the atomic physics community in connection with the determination of accurate abundances for phosphorus in the solar photosphere, in solar twins, in the infrared spectrum of Messier 77 galaxy (NGC1068).
