Abstract
Positronium formation occurs mainly by a reaction between the positron and an excess electron in the positron spur in liquids, solids, and high density polyatomic gases [1.35]. The positron spur is the terminal spur of the positron track formed when the positron loses the last part (∼500 eV) of its kinetic energy. Both particles are almost, or completely, thermalized at the time of the reaction. However, in frequent cases the particles are not fully solvated, i.e., not in thermal equilibrium with the solvent, when they form Ps.
