摘要：

We investigate various proporties 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 2gamma 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.
