Abstract
The positron annihilation lifetime has been applied to study the effect of atmosphere (air and oxygen gas) on A-type zeolite (MS-4A). The measurements were performed at 1 atm of oxygen gas and at 1 atm of air media at room temperature. The lifetime spectra were analyzed using two methods: 1) average results of the ortho-positronium (o-Ps) lifetime and its intensity obtained by PATFIT program and 2) o-Ps lifetime and hole volume distributions given by Bayes' theorem and the maximum entropy principle (MELT program). The results showed that the o-Ps lifetime components have small values when the sample was in oxygen gas medium compared with those in air medium and vacuum. This indicated that both the inhibition and quenching effects of the oPs parameters due to oxygen gas are taking place in MS-4A.
