摘要：
Ortho-positronium (o -Ps), which self-annihilates into 3 with a lifetime of 142ns, may be quenched through various interactions with atoms and molecules. The quenching process of o -Ps in gases, (i) pick-off quenching, (ii) attachment (chemical) quenching, (iii) spin conversion quenching through electron exchange, (iv) spin conversion quenching through spin-orbit interaction with a heavy atom, are reviewed.
