✦ Synopsis

The magnetic field dependence of the lifetimes and energy states of positronium complexes is calculated for a three-spin-l/2 system including an electron, a positron, and a nucleus. It is demonstrated that coupling of a magnetic nucleus and anisotropy of the system has a pronounced effect on the magnetic quenching behaviour, in particular near avoided crossings of magnetic energy levels.
