摘要：
The magnetic field dependence of the lifetimes and energy slates of positronium complexes is calculated for a three-spin-1/2 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.
