Relativistic frequency shifts in Cr, Ti, Fe, Ni, Ca, Na, and V to search for variations in the fine-structure constant
Abstract
Sensitivity of the frequencies of 22 atomic transitions to the variation of the fine-structure constant α is calculated. The findings are to be used in a search for possible variations of α across our galaxy using high-quality spectroscopic data for stars similar to our sun.
