A determination of fundamental constants using HD+ ion and atomic hydrogen spectroscopy data

A determination of fundamental constants using HD+ ion spectroscopy data is discussed from comparisons between precision measurements and accurate theoretical predictions by taking into account recent measurements and updated CODATA values of the fundamental constants. The deuteron-proton mass ratio is determined with an uncertainty of 10(-9). The ratio between the HD+ reduced mass and the electron mass is determined with an uncertainty of 7.3 X 10(-10). The Rydberg constant, the proton-electron mass ratio and the deuteron-electron mass ratio are consistently determined with 10(-9), 10(-6), and 10(-6) level uncertainties from an adjustment of the (v,L)=(0,0)->(0,1) and (v,L)=(0,2)->(8,3) HD+ ion transitions and of the (n,l,j,f)=1S(1/2)f=1 -> 2S(1/2)f=1 atomic hydrogen transition. The result of the adjustment provides a test of the consistency of the two-body and three-body quantum electrodynamics energy level calculations for the atomic hydrogen and the HD+ ion.
