| dc.description.abstract | The positron annihilation lifetime spectroscopy (PALS) of cavansite crystals collected from Wagholi, Pune district of Western Maharastra, India were characterized by Co-60 gamma radiation with an irradiation dose of 1 Mrad and 3 Mrad at ambient conditions. The influence of gamma-irradiation on the pore size and its content on cavansite structure were examined. The studies suggest ortho-positronium (o-Ps) lifetime (tau(3)) and intensity (I-3) decreased upon gamma-irradiation. The decreased o-Ps lifetime (tau(3)) is attributed to the collapse of the framework structure of cavansite crystal. In addition, the reduction in o-Ps intensity (I-3) is known to decrease o-Ps annihilation sites because of free radical reactions. | - |
