激光促进反氢原子的形成

LASER ASSISTED ANTIHYDROGEN ATOM FORMATION IN COLLISIONS OF ANTIPROTONS WITH POSITRONIUM

作为原子物理对邻近学科的应用,在本文中,我们探讨激光促进反氢原子形成的可能性。我们具体讨论了激光对过程Ps+P→H+e的影响。我们的结果表明,在合适的条件下,激光能使反氢原子的产额有明显的提高。

The possibility of laser-assisted antihydrogen atom formation in collisions of antiprotons with positronium is discussed in the present paper using an improved perturbation theory of multiphoton transitions and the Born approximation. Our results show that a strong laser field may assist the formation of antihydrogen atom in antiproton-positronium collisions in some cases. A mechanism is proposed for explaining such an enhancement in the antihydrogen atom formation cross section.
