“…In principle, all angular momenta transfers that satisfy the angular momentum and parity conservation should be taken into account. However, that transfer angular momenta higher than the lowest one, contribute very little to the decay rate [28][29][30], and are difficult to be evaluated. Therefore, only the lowest angular momentum transfer is taken into account, and also for unfavored α-decay.…”

The advent and intensive use of new detector technologies as well as radioactive ion beam facilities have opened up possibilities to investigate alpha, proton and cluster decays of highly unstable nuclei. This article provides a review of the current status of our understanding of clustering and the corresponding radioactive particle decay process in atomic nuclei. We put alpha decay in the context of charged-particle emissions which also include one-and two-proton emissions as well as heavy cluster decay. The experimental as well as the theoretical advances achieved recently in these fields are presented. Emphasis is given to the recent discoveries of charged-particle decays from proton-rich nuclei around the proton drip line. Those decay measurements have shown to provide an important probe for studying the structure of the nuclei involved. Developments on the theoretical side in nuclear many-body theories and supercomputing facilities have also made substantial progress, enabling one to study the nuclear clusterization and decays within a microscopic and consistent framework. We report on properties induced by the nuclear interaction acting in the nuclear medium, like the pairing interaction, which have been uncovered by studying the microscopic structure of clusters. The competition between cluster formations as compared to the corresponding alpha-particle formation are included. In the review we also describe the search for super-heavy nuclei connected by chains of alpha and other radioactive particle decays.

“…Therefore if we propose the independence of α-cluster formation probability on the angle θ, then the α-particles should be emitted mainly at angle θ = 0 • (see also [23,25,30,31,32,33]). A similar effect is wellknown in the case of sub-barrier fusion reactions between spherical and deformed nuclei [34,37].…”

“…Therefore α-nucleus potential should depend on the angle θ between the direction of α-emission and the axial-symmetry axis of the deformed nucleus. Both the α-decay width and the transmission coefficient for tunnelling through the barrier are strongly dependent on θ [20,22,23,24,25,26,30,31,32,33]. This effect is considered in detail in microscopic models [23,24,25,26].…”

α-nucleus potential for α-decay and sub-barrier fusion

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