The set of parameters for {alpha}-nucleus potential is derived by using the data for both the {alpha}-decay half-lives and the fusion cross sections around the barrier for reactions {alpha}+{sup 40}Ca, {alpha}+{sup 59}Co, and {alpha}+{sup 208}Pb. The {alpha}-decay half-lives are obtained in the framework of a cluster model using the WKB approximation. The evaluated {alpha}-decay half-lives and the fusion cross sections agreed well with the data. Fusion reactions between {alpha} particles and heavy nuclei can be used for both the formation of very heavy nuclei and spectroscopic studies of the formed compound nuclei.
