“…In this process dissipation (intrinsic excitations during transfer) and the evo lution of deformation must be avoided because the expense in energy will reduce the tunnelling probability. Numerous studies of coupled channel phe nomena in fusion reactions, related to inelastic excitations and transfer pro cesses [7,[66][67][68][69]76,77], have shown that the tunnelling process is embedded in a complicated multidimensional rearrangement process.…”

“…Subsequently, a number of theoretical calculations were performed to predict absolute α decay width, to extract nuclear structure information, and to pursue a microscopic understanding of α-decay phenomenon. These studies are based on various theoretical models such as the shell model, fissionlike model, and cluster model [18][19][20][21][22][23][24][25][26][27][28][29].

A global calculation of favored α-decay half-lives of both even-A and odd-A deformed nuclei is carried out in the framework of a deformed version of the density-dependent cluster model (DDCM). The influence of nuclear deformation on α-decay half-lives is taken into account in the deformed DDCM. The microscopic potential between the spherical α particle and the deformed daughter nucleus is evaluated numerically from the double-folding model by the multipole expansion method. The deformation and orientation dependence of the α-core potential is analyzed and discussed. The formulas of the deformed DDCM are presented in detail, and a large number of numerical calculations of medium and heavy nuclei with available data are completed. The total number of α emitters calculated in this article is 485, and this covers the nuclei with Z = 52-110. This is a complete study of α-decay half-lives on both even-A and odd-A nuclei with deformed microscopic potentials. The numerical results obtained by the deformed DDCM are in good agreement with the experimental data.

Summary. -Microscopic calculations of cluster decay widths, which have been one of the recurrent challenges of nuclear theory for many years, require a good description of the preformed cluster in the mother nucleus. Since the cluster being emitted is formed either at the nuclear surface or beyond it, a reasonable microscopic description of the clustering requires the use of a realistic finite single-particle potential, including its continuum. In this paper, recent developments in the dynamical theories of cluster decay are reviewed with special emphasis on the influence of the continuum in the decay process.The ordinary shell models, including the BCS approach, are discussed. Also clusterlike shell model theories, which incorporate the most important effects of the continuum, are presented.By discussing diverse calculations, it is concluded that the most essential prerequisite for a realistic model of the mother nucleus is that it should correctly describe the cluster correlation in the surface region as well as the clustering at large distances. This implies, on the one side, that the proton-neutron interaction is indispensable and, on the other, that high-lying configurations, reflecting the influence of the continuum, have to be taken into account properly.I will mainly present the work that I have done in collaboration with a number of researchers, as shown in the list of references. For a recent and detailed review of this work see ref.[1], from which much of the material to be presented here is taken.The formation and decay of clusters in nuclei is a time-dependent problem. It is therefore a very difficult problem, particularly because the initial state is not well defined. One
