We report a refined determination of muonium 1S-2S 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 1S-2S transitions are determined with a precision of 2.4 × 10 −10 and 1.7 × 10 −10 , respectively. An updated muonium-deuterium 1S-2S 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.

“…The most recent result was reported by the Hänsch group in 2011, in which they determined the transition to a fractional frequency uncertainty of 4.2 × 10 −15 [10]. By that time, the UV laser source had evolved to an all solid state system that produced 13 mW of 243 nm cw radiation.…”

“…Very precise experiments correspond to the measurements of the spectroscopic properties of this atom. In particular, the frequency measurements of the two-photon transitions 2s-1s [1][2][3] and 3s-1s or 3d-1s [4,5] in hydrogen have established the highest order of accuracy for the spectroscopic experiments. On the other hand, the recent success in the production of antihydrogen atoms offers the possibility for a detailed comparison of spectroscopic properties of the H andH atoms.…”

We analyze the influence of an external electric field on the ns and np Rydberg states. The impact of an electric field leads to a significant modification of the decay rate. Namely, the additional (linear and quadratic in the field) terms arise in the differential transition probabilities. In contrast to the quadratic term, the linear summand leads to a difference of the hydrogen (H) and antihydrogen (H) spectra. However, this difference vanishes after the integration over photon-emission directions and does not contribute to the total emission probability. The quadratic term results in the significant change of the total decay rate and level width, respectively. The analysis of the linear and quadratic terms depending on the field strength is discussed.
