Positronium (Ps) formation by weakly localized long-lived electrons (trapped electrons or anions) and positrons at low temperatures successfully explained the Ps formation enhancement at low temperatures observed in polymers and molecular solids. This Ps formation is completely different from Ps formations by Ore process or spur process. The phenomena expected by this Ps formation mechanism, such as an effect due to visible light exposure, the density effect of weakly localized electrons and the delayed Ps formation were successfully observed as the experimental evidence of this Ps formation process. Some possibilities for application of this new Ps formation were also given. One is a new idea for estimation of spin polarity positrons. Another is the possibility of application to study the local molecular motion by observing the decay of Ps formation possibility by this Ps formation process.
