“…Thirteen new β-delayed neutron groups are observed. 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].…”

“…Due to large decay energies (Q values) in neutron-rich nuclei, daughter nuclei can be populated to highly excited states, which provides a good ground to study the structures of neutronrich nuclei by measuring the γ spectroscopy or particle emissions. Using the PKU neutron sphere and wall, the experiments which studied the β decays of neutron-rich 18,21 N were performed at HIRFL in Lanzhou [53][54][55][56]. The first spectroscopic data for the β decay of 21 N was obtained with β-n, β-γ, and β-n-γ coincidence measurements.…”

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.

“…This approach was first demonstrated in Ref. [64] and has subsequently been used to study mass-separated ion beams of 137,138,140 I, 135,136 Sb, and 144,145 Cs [111,112] delivered by the CARIBU facility at Argonne National Laboratory.…”

“…In addition, for 13 neutron-rich nuclei the β-decay half-life was measured for the first time: 140−142 Sb, 139−144 Te, 144−146 I, and 148 Xe. This led, for example, to tiny changes in the recommended half-lives for the P 1n standards 144,145,146 Cs: Based on Q values deduced from the Atomic Mass Evaluation (AME) 2016 for neutron-rich nuclides [33,124], a total of 221 experimentally observed nuclides were identified as known or potential β-delayed neutron emitters in Ref. [35].…”
