A new method of spectroscopy PsARS (positronium annihilation ratio spectroscopy) has been developed where ratios are determined of detected coincidence signals resulting from the three γ-ray decay of ortho-Ps to coincidence signals from the two γ d

Positronium (Ps) produced by 4 to 40 eV positrons colliding with Ne, Ar, Kr, CO2, and O2 is investigated by measuring the ratio of signals of two gamma rays in coincidence resulting from (a) three gamma annihilation of ortho-Ps and (b) two annihilati
