Calculation of the dependence of transition frequencies on the fine structure constant and the search for variation of alpha in QSO spectra

J. C. Berengut, V. A. Dzuba, V. V. Flambaum +1

We calculate the dependence of atomic transition frequencies on the fine structure constant, $α = e^{2} /ℏ c$ , for some ions of Ti, Mn, Na, C, and O. The results of these calculati…

Space-time variation of the fine structure constant and evolution of isotope abundances

M. G. Kozlov, V. A. Korol, J. C. Berengut +2

At present several groups are analyzing astrophysical data in a search for time-variation of the fine structure constant $α$ . Here we discuss how to exclude systematic effects caus…
