Abstract
We report a refined determination of muonium 1-2 transition frequency and its isotope shift with deuterium by recalibrating the iodine reference lines using an optical frequency comb. The reference lines for the muonium and deuterium 1-2 transitions are determined with a precision of and , respectively. An updated muonium-deuterium 1-2 isotope-shift frequency is derived from these references to be 11 203 464.9(9.2)(4.0) MHz, in agreement with an updated bound-state quantum-electrodynamics prediction based on 2010 adjustments of Committee on Data for Science and Technology and 2.3 times better in the systematic uncertainty than V. Meyer et al. [Phys. Rev. Lett. 84, 1136 (2000)].
