Precise Computation of Energy Levels and Radiative Lifetimes in the s, p, d, and f Sequence of Hydrogen Isotope, with Natural Line Widths

Abstract

Energy levels and Radiative lifetimes in Deuterium for the following: ns ²S_1/2(n≥2), np²P^o_(1/2,3/2)(n≥2), nd ²D_(3/2,5/2)(n≥3), and nf ²F^o_(5/2,7/2)(n≥4) sequence have been  evaluated with uncertainties in energies caused due to uncertainty principal. Theoretical calculations performed utilizing the Weakest Bound Electron Potential Model Theory (WBEPMT). Both sets of data show quite an excellent agreement with the experimental data listed at NIST.  This theoretical computation is also a continuation of the work by Raza. S. et al. in Neutral Hydrogen. The high ‘n’ (principal quantum number) values for both sets  of data are presented very first time by utilizing WBEPMT.

Keywords: Energy levels, Radiative lifetimes, Quantum defects, Weakest bound electron, Natural line width.
