Abstract: The half life time and other characteristics for the emission of clusters like 8Be, 16O, 20Ne, 24Mg, 28Si and 32S have been computed within the Coulomb and proximity potential model and the predicted half life time values have been compared with other models. It is found that 8Be emission from 112Ba is most favourable for measurements with the lowest half life time value [log10 (T1/2) = 7.23s]. Geiger-Nuttall (GN) plots for all clusters have been studied and are found to be linear. It is found that the inclusion of proximity potential will not produce any deviation from the linear nature of GN plots. The nuclear structure and shell effects are evident from the observed variation in slope and intercept of GN plots.
