Measuring chemical evolution and gravitational dependence of α using ultraviolet Fe v and Ni v transitions in white-dwarf spectra

Flambaum, V. V.; Berengut, J. C.; Ong, A.

In this paper, we present the details of the ab initio high-precision configuration interaction and many-body perturbation theory calculations that were used by Berengut [Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.111.010801 111, 010801 (2013)] to place limits on the dependence of the fine-structure constant, α, on the gravitational field …
