How long it takes para-positronium AND ortho-positronium to become para-positronium OR ortho-positronium? Decoherence of positronium in a matter
para-positronium AND ortho-positronium para-positronium ortho-positronium
2010/11/11
Because of small gap between the energy of para-positronium (p-Ps) and ortho-positronium (o-Ps) it was assumed the possibility of the existence of superposition of p-Ps and o-Ps states as a result of...
Measurement of the ortho-positronium confinement energy in mesoporous thin films
ortho-positronium mesoporous thin films

In this paper, we present measurements of the ortho-positronium emission energy in vacuum from mesoporous films using the time of flight technique. We show evidence of quantum mechanical confinement i...
