Hydrogen-Antihydrogen Molecule and Its Properties

摘要

The metastability of the four-body system is discussed from the point of view of radiative rearrangement collisions of the hydrogen and antihydro-gen. Such collisions lead to the formation of an intermediate molecular state which further decays into positronium and protonium or is destroyed via annihilation. We present calculations of the lifetime of the system and the branching ratios for Coulombic decay and annihilation.
