Descrição: The half-lives of cluster radioactivity are investigated using a modified generalized liquid-drop model (MGLDM). The radioactive decay with different cluster emissions in the isotopes of He, Li, Be, Ne, Na, Mg, Al, Si, P Ar, K and Ca nuclei are studied. The cluster radioactivity half-lives have been evaluated within WKB integral method. The estimated cluster decay half-lives from the present work precisely reproduce the experimental data. Predictions are made in the even superheavy nuclei in the atomic number range 104 ≤ Z ≤ 126 . The role of Coulomb effect ( Z 2 / A 2 / 3 ), asymmetry effect ( ( N - Z ) 2 / A ), pairing effect ( A ) and shell effect on cluster radioactivity are studied.
