Using Strong Laser Fields to Produce Antihydrogen Ions
by Keating, Christopher M., Ph.D., Portland State University, 2018, 134; 10846288
Abstract (Summary)

We provide estimates of both cross section and rate for the stimulated attachment of a second positron into the (1s2 1Se) state of the + ion using Ohmura and Ohmura’s (1960 Phys. Rev. 118 154) effective range theory, Reiss’s strong field approximation (1980 Phys. Rev. A 22, 1786), and the principle of detailed balancing. Our motivation for producing + ion include its potential to be used as an intermediate state in bringing antihydrogen to ultra-cold (sub-mK) temperatures required for a variety of studies, which include both spectroscopy and the probing of the gravitational interaction of the anti-atom. We show that both cross section and rate are increased with the use of a resonant laser field.
