“…In a previous work of cluster-decay calculations, we suggested a cluster potential which is a simple folding of the single-particle mean-field potentials of the cluster nucleons [8,9]. The cluster potential was folded to reproduce the experimental energy of the cluster decay [8,9].…”

Using a new local cluster potential, cluster structures around double shell closures have been investigated. The calculations of spectra including electromagnetic transitions are in reasonable agreement with experimental data. Besides the nuclei, 20 Ne, 44 Ti, 60 Zn, and 212 Po, which have been intensively analyzed by cluster models, we have also studied two other good candidates, 52 Ti and 136 Te, for α-cluster structure in neutron-rich regions. In 136 Te, the unexpectedly small B(E2; 0 + → 2 + ) would be due to the cluster characteristic. The new cluster potential without any readjustment of the parameter values has been also applied to the investigations of possible 6 He-cluster structure in nuclei, 22 Ne, 46 Ti, 54 Ti, 62 Zn, and 138 Te, which have the same doubly magic cores as the α-cluster nuclei above. Similarly good results can be obtained, compared with experimental data. It is an advantage that the new cluster potential suits the different types of cluster structures with a set of fixed parameters which do not need any readjustment for different cluster-core structures.

“…In our previous works [15,16,17,18,19,20], we constructed folded mean-field-type cluster potentials based on microscopic Skyrme-Hartree-Fock [15,16,17] or phenomenological WoodsSaxon potentials [18,19,20].

Abstract. Assuming that the α particle is a structureless point particle with two protons and two neutrons, we construct a mean-field-type cluster potential based on the Woods-Saxon potential with a folding factor which is to satisfy the quantization condition of a quasibound cluster state. The folded Woods-Saxon cluster potential has been successfully applied to the calculations of α-particle decay in light and superheavy nuclei. The standard values of the Woods-Saxon parameters were used without any adjustment. The calculated α-decay widths or lifetimes agree generally with experiment. Such a cluster potential leads to a consistent description of single-particle and cluster motions.

“…The half-life for the β decay of 21 N is determined to be 82.9±7.5 ms which gave an accurate measured value so far [54]. Theoretical studies cover many different topics including cluster structures and decays [57][58][59][60][61][62], resonances in unstable nuclei [63][64][65], heavy and superheavy nuclei [66][67][68][69][70] (see [71] for the experimental synthesis of 271 Ds), rotational states [72][73][74][75][76][77][78][79][80], shape transitions [81][82][83], mean-field models [84][85][86][87], nuclear symmetry energy [88][89][90][91][92][93] and some other topics [94,95]. The theoretical works have motivated model developments, and also provided many useful theoretical predictions and explanations for the experiments.…”

In the paper we review the recent progress of studies in unstable nuclei, mainly affiliated with the facilities of radioactive ion beams in China, including both experimental and theoretical aspects of researches. Many experiments for reactions, decays and structures have been performed targeting better understandings of properties of unstable nuclei. Special experimental measurements related to nuclear astrophysics have been done to seek insights into the processes of syntheses of elements in the universe. Theoretical calculations have provided many useful predictions on the behaviors of unstable nuclei, with model developments. Studies covered many mass regions from light to superheavy nuclei, giving plenty of information about the structures of unstable nuclei, towards the limits of existence of atomic nuclei. unstable nuclei, radioactive ion beams, nuclear astrophysics, experiment, theory Citation: Xu F R.
