Precision spectroscopy of the hydrogen molecular ions HD$^+$ (1211.6810v2)
Published 29 Nov 2012 in physics.atom-ph
Abstract: Expectation values of the Breit operators and the $Q$ terms are calculated for HD$+$ with the vibrational number $v=0-4$ and the total angular momentum $L=0-4$. Relativistic and radiative corrections to some ro-vibrational transition frequencies are determined. Numerical uncertainty in $R_{\infty}\alpha2$ order correction is reduced to sub kHz or smaller. Our work provides an independent verification of Korobov's calculations [Phys. Rev. A {\bf74}, 052506 (2006); {\bf77}, 022509 (2008)].
