摘要：

The decay of unstable nuclei which disintegrate with simultaneous emission of few charged fragments is studied. The decay scenario is determined by means of consideration of the Coulomb-correlated quasi-classical motion of outgoing clusters in the sub-barrier region. It is shown that the special solutions which describe the self-similar expansion are particularly important to describe penetration through a multi-dimensional potential barrier. The correlated motion of outgoing particles at the final stage of sub-barrier penetration leads to the energy and angular correlations of emitted particles.
