WebThis bound state is an analogue of the hydrogen atom [1]. Depending on mutual spin orientation of the involved particles, the bound system, called positronium (Ps), can exist in two substates: singlet, S = 0 ( para -Ps, p -Ps) or triplet, S = 1 ( ortho -Ps, o -Ps). The annihilation modes of these two spin states are different due to the pairity ... WebPositronium is typically formed with probability on the order of 50% at gas pressures of 1 atm.
