Published 2021-11-01“…The relativistic shift energy ${Δ}E_{{msp}}^{{tot}}\left( n,\alpha,A,B,V_{0},\Theta,\sigma,\chi,j,l,s,m \right)$ and the perturbative nonrelativistic corrections $\Delta E_{{msp}}^{{nr}}\left( n,\alpha,A,B,V_{0},\Theta,\sigma,\chi,j,l,s,m \right)$ appeared as a function of the parameters $\left( \alpha,A,B,V_{0} \right),$ the parameters of noncommutativity $\left( \Theta,\sigma,\chi \right),$ in addition to the atomic quantum numbers $\left( n,j,l,s,m \right).$ In both relativistic and nonrelativistic problems, we show that the corrections on the spectrum energy are smaller than the main energy in the ordinary cases of RQM and NRQM. …”
