High-precision spectroscopy of hydrogen molecular ions

摘要

In this paper, we overview recent advances in high-precision structure calculations of the hydrogen molecular ions(H+2and HD+), including nonrelativistic energy eigenvalues and relativistic and quantum electrodynamic corrections. In combination with high-precision measurements, it is feasible to precisely determine a molecular-based value of the protonto-electron mass ratio. An experimental scheme is presented for measuring the rovibrational transition frequency(v, L) :(0, 0) →(6, 1) in HD+, which is currently underway at the Wuhan Institute of Physics and Mathematics.
