Numerical evaluations of the isotopic shifts and lowest-order QED corrections for the ground $1^{1}S-$states of the ${}^3$He and ${}^4$He atoms

Abstract

The both mass-dependent and field shift components of the isotopic shifts and the lowest order QED corrections for the ground (singlet) $1^{1}S(L=0)-$states of the ${}^3$He and ${}^4$He atoms are determined to high accuracy. For the same states we also evaluated the lowest-order QED corrections and the corresponding recoil (or finite mass) corrections. In our calculations we have used the new (corrected) formula for the recoil correction to the lowest-order QED correction which can be applied to atoms/ions with arbitrary nuclear charge $Q\ge 1$.
