    Abstract: In this work, we applied the first order time independent Rayleigh–Schrödinger Perturbation Theory, as an approximation method to calculate numerically the corrections in atomic spectra due to nuclear structure effects. The results showed that the nuclear structure effects distort the atomic spectra in different ways: The combined fine structure ef... Show More
