<p> We provide estimates of both cross section and rate for the stimulated attachment of a second positron into the (1<i>s</i><sup>2</sup> <sup> 1</sup><i>S<sup>e</sup></i>) state of the <i>H¯ </i><sup>+</sup> 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 <i>H¯</i><sup>+</sup> 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.</p><p>
