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.

Coulomb and nuclear dissociation of 17 Ne on light and heavy targets are studied theoretically. The dipole E1 strength function is determined in a broad energy range including energies of astrophysical interest. Dependence of the strength function on different parameters of the 17 Ne ground state structure and continuum dynamics is analyzed in a three-body model. The discovered dependence plays an important role for studies of the strength functions for the three-body E1 dissociation and radiative capture. The constraints on the [s 2 ]/[d 2 ] configuration mixing in 17 Ne and on pwave interaction in the 15 O+p channel are imposed based on experimental data for 17 Ne Coulomb dissociation on heavy target.

The fragment separator ACCULINNA-2 has been constructed, approved by the Programme Advisory Committee (PAC) and commissioned in the G.N. Flerov Laboratory of Nuclear Reactions (JINR, Dubna) in 2017. It was tested with the 15 N beam at the energy of 49.7 MeV/nucleon. The secondary beams 6 He and 12 Be produced in the beryllium target were obtained with purities and intensities predicted by the code LISE++. Here, we list the most meaningful and challenging experiments on the light dripline nuclei at ACCULINNA, which should be clarified at ACCULINNA-2: (i) the search for the minor 2p-decay branch of the first excited state of 17 Ne, the Γ 2p /Γ γ width ratio; (ii) study of break down of the shell closure in the doubly magic 10 He in the 3 H(8 He,p) 10 He reaction; (iii) study of the β-delayed proton emission in 26 P and 27 S, which offers insight into the structure of the initial and the final states of these exotic nuclei. Among the first-day experiments is a study of the low-energy resonance states of 7 H anticipated for the 4n decay.
