Transition frequency shifts with fine-structure constant variation for Fe I. Isotope shift calculations in Fe I and Fe II

In this paper we calculated the relativistic corrections to transition frequencies (q factors) of Fe I for the transitions from the even- and odd-parity states to the ground state. We also carried out isotope shift calculations in Fe I and Fe II. To the best of our knowledge, the isotope shift in Fe I was calculated for the first time.
