Screening parameters for the relativistic hydrogenic model

We present a Relativistic Screened Hydrogenic Model (RSHM) where the screening parameters depend on the variables (n, l, j)(n, l, j) and the parameters (Z, N)(Z, N). These screening parameters were derived theoretically in a neat form with no use of experimental values nor numerical values from self-consistent codes. The results of the model compare favorably with those obtained by using more sophisticated approaches. For the interested reader, a copy of our code can be requested from the corresponding author.
