摘要
The time taken for positrons to reach thermal equilibrium in a number of simple molecular gasps has been estimated using the gas mixture technique devised by Paul and Leung (Paul D A L and Leung C Y Can. J. Phys. 46 2779-88), Times below 100 ps Amagat have been found for a number of species, suggesting their use as efficient coolers for rapid-cycle positron traps and accumulators.
