Abstract
We investigate various properties of resonance states as well as bound states of positronium molecule. We use the stochastic variational method to calculate the precise energies of the bound states. A primary decay mode of the bound states is 2γ pair annihilation and other decay branches are small except for the electric dipole transition between the P state and the ground state of the positronium molecule. We calculate the resonance states with the complex scaling method and obtain several 0+ resonances below the Ps− +e + threshold.KeywordsDecay WidthResonance StateElectric Dipole TransitionPair AnnihilationTotal Decay RateThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
