An extension of the generalized density-dependent cluster model (GDDCM) is presented to study {alpha}-cluster structure above doubly closed shells. In all cases, the microscopic {alpha}-core potential is numerically constructed in the double-folding model with CDM3Y6 nucleon-nucleon interactions plus proton-proton Coulomb interactions. The properties of intraband E2 transitions and {alpha} decays are calculated by the exact solution of the Schroedinger equation with appropriate boundary conditions. It is found that the enhanced B(E2) transition strengths are well reproduced without any effective charge and the calculations of {alpha}-decay properties show good agreement with the available experimental data. This indicates that the GDDCM has universal applicability and equal validity regardless of whether the {alpha}-cluster states are in light or heavy nuclei.
