AbstractAbstract
[en] The lifetime of the ortho-positronium in the zeolite 4A, partially dehydrated, changes to three characteristic modes. The first mode could be associated with the water elimination of the small β cavity of this zeolite. At the end of this first dehydration process it is estimated a cavity radius, R = 33.8 nm. The other two types of variation of lifetime of ortho-positronium would be associated with the water elimination of the α great cavity and of the rest of the zeolite. From the zeolite 4A totally dehydrated and of the zeolite 4A exchanged with Co (II) and MN (II), also dehydrated radius are respectively determined for the α great cavity of R = 48.1, 54.5 and 56.5 nm.
