“…It would provide -by comparison with existing high-precision data on normal hydrogen -an opportunity to investigate questions related to matter-antimatter symmetries, and would allow in particular for tests of quantum-electrodynamics in a system of bound antiparticles. It would open up the possibility to study the interaction of hydrogen and antihydrogen atoms, a repeatedly discussed problem [14]. Furthermore, since this system is electrically neutral, experiments may be conceived to test the interaction of antimatter with the gravitational field.…”

The electron-ion capture rate for low electron energies is calculated for various electron velocity distributions. Capture rates for electron-ion recombination stimulated by irradiation with light are evaluated. The results are applied to electron cooling and to positron-antiproton recombination to form antihydrogen. It is shown that laser-induced capture is a powerful method to study the electron cooling process and to maximize the antihydrogen rate. With this technique a pulsed antihydrogen beam of selectable energy and well collimated with an intensity of a few atoms per second can be anticipated.

“…Meanwhile, theH + H system has deeper scientific significance since it is one of the simplest and most fundamental matter-antimatter combinations. So far, a lot of theoretical studies have been done on this matter-antimatter collision system in atomic physics [7][8][9][10][11][12][13][14][15][16][17][18]. In most of these studies, the Born-Oppenheimer (BO) approximation is a starting point for treating the atomic four-body dynamics in H + H, and first-order perturbation theory is applied to the rearrangement reaction.…”

Metastable compound states of an antiproton and a hydrogen atom

The stability of antiproton-hydrogen compound states (pH) is investigated theoretically. ThepH compound state has decay channels of atomic electron detachment (→e − +pp) and hadronic pair (p-p) annihilation, and hence it cannot be permanently stable even if the dissociation channel (→p + H) is energetically closed. In this paper, information on the metastablepH states at energies below the dissociation limit is obtained by analyzing low-energy resonances in e − +pp scattering. The scattering calculation is carried out by using an R-matrix method, which also allows for the annihilation channel simultaneously. The metastable states are found to be identified as vibrational levels supported by a Born-Oppenheimer (BO) potential. The energy-level widths attributed to the electron detachment and the annihilation are also calculated using a model based on the BO picture.

“…There has been interest in calculations on the interaction of H with H, since the 1970s, Junker and Bardsley [206], Morgan and Hughes [207], Ko los et al [208], Campeanu and Beu [209], Shylapnikov et al [210]. However, the work on the preparation of H described above has generated greater theoretical interest in this system, Armour et al [169,211,212,213,214,215] Jonsell, Froelich et al [216,217,218,219,220,221,222], Sinha and Ghosh [223], Voronin and Carbonell [224].…”

Stability of few-charge systems in quantum mechanics

We consider non-relativistic systems in quantum mechanics interacting through the Coulomb potential, and discuss the existence of bound states which are stable against spontaneous dissociation into smaller atoms or ions. We review the studies that have been made of specific mass configurations and also the properties of the domain of stability in the space of masses or inverse masses. These rigorous results are supplemented by numerical investigations using accurate variational methods. A section is devoted to systems of three arbitrary charges and another to molecules in a world with two space-dimensions.
