These calculations were motivated by a recent study [Zammit et al., Phys. Rev. A. 100, 042709 (2019)] that proposed an experimental scheme by which antihydrogen molecular ions could be produced by laser excitation of metastable antihydrogen atoms held in a magnetic trap. Calculations were performed for temperatures less than 1 K, and high-energy fitting formulas were used to estimate rates at the low energies required for the experiment. It was predicted that at lower energies AI would have a higher rate than PI.
The present work extends the previous study by performing scattering calculations that incorporate fine structure and Lamb shift at lower energies (<10-7 Eh). The resulting rates are compared with those extrapolated from high-energy fitting formulas. The low-energy behavior differs from what was predicted from the high-energy fits, with PI being the dominant ionization process at all temperatures. The relative efficiency, however, is within a factor of three at temperatures required by the experimental scheme.
