The half-life for the Alpha-decay of 212 Po is calculated within a harmonic oscillator representation. Clustering induced by the nuclear interaction appear by considering a large configuration space. The role of clusterisation in the alpha-decay process is clearly demonstrated. It was shown that as soon as four-particle cluster is formed on the surface of the nucleus a broad region appears in which the ratio between theoretical half-lives and experimental ones is independent on the channel radius. That is the important result itself which indicates that the old problem of strong dependence of alpha-decay widths on arbitrary parameter of channel radius can be solved by describing the alpha-decay as the disintegration of the initial state in which alpha clustering occurs. The role of proton-neutron interaction proved to be decisive in the formation of the stable four-particle cluster.
