摘 要：We have measured the positron lifetime spectra of zeolite 13X as a function of exposed air *** lifetime components have been obtained and properly *** longer lifetimes τ_(s) and τ_(4) are attributed to ortho-positronium annihilating in the β-cage and supercage in zeolite *** interGsting observation is th&t the positron annihilation parameters vary significantly with the exposed air *** is interpreted in terms of the spinof positronium with paramagnetic oxygen.
