The cluster radioactivity exhibited by Gd128-134 isotopes with the exotic emission of certain clusters like He-4, Be-8, C-12, O-16, Ne-20, Mg-24, and Si-28 have been studied. The half-life values for different cluster emissions were calculated by considering the interacting potential barrier as a sum of Coulomb potential and proximity potential. The emission of Si-28 cluster from Gd-128 isotope leads to the formation of Sn-100 daughter nucleus which is a doubly-magic nucleus. Hence, the Si-28 cluster emission is expected to have the lowest half-life and therefore highly favorable for measurements. Our calculations also corroborate this point and thus emphasize the role of Sn-100 in the exotic decay process. The Geiger-Nuttall plots for different cluster emissions were found to be linear, but with different slopes and intercepts. We have studied the variation of these slopes and intercepts as a function of the proton number of clusters. Based on this, we have arrived at a handy and convenient expression for half-life values for emissions of various clusters from Gd128-134 isotopes.
