説明
Abstract We investigate the spectrum of the positronium (Ps) molecule consisting of two electrons and two positrons by the stochastic variational method (SVM). By calculating the energies of states with Lπ=0±,1± and 2±, we confirm that only four states, 0+(A1), 0+(B2), 0+(E) and 1−(B2), are bound. We investigate the various properties of these bound states as well as the decay probabilities for the 2γ emission by electron–positron annihilation leaving a particular Ps final state. The binding energies of a biexciton, a Coulomb four-body system analogous to Ps2, are also examined as a function of the electron–hole mass ratio.
