Decay half-live of several clusters between 14C and 34Si emitted from various heavy deformed nuclei with mass numbers in the range 221≤A≤242 are calculated using nuclear Woods-Saxon (VN(r, θ)), Coulomb (VC(r, θ)) and rotational (Vl(r)) potentials considering deformation for both daughter and cluster and spherical configuration for them. Half-live of these decays are also obtained using a semi-empirical formula. Obtained results considering deformation are compared with the half-live of spherical configuration, results of a semi-empirical formula as well as the available experimental data. The comparison indicates that the calculated half-lives considering deformation are better agreed with the experimental data than the results of spherical configuration and the out put of semi-empirical formula. Also, The obtained results using deformation is better confirmed the Geiger-Nuttall low of alpha decay, especially for emission of light clusters as expected.
