Semi-empirical Calculation of Oscillator Strengths and Lifetimes for the P V Spectrum C′alculos Semi-Emp′?ricos de Intensidades de Osciladores e Tempos de Vida para Espectro P V

摘要

The semi-empirical oscillator strengths (gf) and the lifetimes presented in this workfor all known P V spectral lines and energy levels were carried out in a multiconfiguration Hartree-Fock relativistic (HFR) approach. In this calculation, the electrostaticparameters were optimized by a least-squares procedure, in order to improve theadjustment to experimental energy levels. This method, produces values gf-valuesthat are closer to those that are expected in intensity observations used for theinterpretation of stellares plasmas spectrograms.
