“…With the help of phenomenological and effective α-core potentials, theoretical studies [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32] have been subsequently proposed for α decay calculations especially in the last two decades. Among these studies, our group provided a unified formula for half-lives of α decay and cluster radioactivity [26] and a new Geiger-Nuttall relation was recently proposed for α decay including the effects of the quantum numbers of α-core relative motion [27] their experimental root-mean-square (rms) charge radii.…”

Recently, experimental researches on the α decay with long lifetime are one of hot topics in the contemporary nuclear physics [e.g. N. Kinoshita et al. (2012) [2] and J.W. Beeman et al. (2012) [4]].In this study, we have systematically investigated the extremely long-lived α-decaying nuclei within a generalized density-dependent cluster model involving the experimental nuclear charge radii. In detail, the important density distribution of daughter nuclei is deduced from the corresponding experimental charge radii, leading to an improved α-core potential in the quantum tunneling calculation of α-decay width. Besides the excellent agreement between theory and experiment, predictions on half-lives of possible candidates for natural α emitters are made for future experimental detections. In addition, the recently confirmed α-decay chain from 294 117 is well described, including the attractive long-lived α-decaying 270 Db, i.e., a positive step towards the "island of stability" in the superheavy mass region.

“…Alpha-decay is a prominent decay channel of heavy and superheavy nuclei (SHN) and acts as an effective probe for the nuclear structure [1][2][3][4][5][6][7][8][9][10][11]. α-decay can provide a powerful and very precise tool to identify new superheavy elements studied at accelerator centers such as Berkeley, GSI, Dubna, GANIL, and RIKEN [12][13][14].…”

“…α decay is one of the most important decay modes for unstable nuclei and has become a powerful tool to investigate the nuclear structure [1][2][3][4][5][6][7][8] and identify new superheavy elements studied at accelerator centers such as Berkeley, GSI, Dubna, GANIL, and RIKEN [9][10][11][12]. In recent years, there has been an increased interest in α decay to excited states of daughter nuclei from both experimental and theoretical sides [13][14][15][16][17][18][19][20].…”

A systematic study on α-decay fine structure is presented for even-even nuclei in the range 78 Z 102. The penetration probability is obtained from the WKB approximation in combination with the Bohr-Sommerfeld quantization condition. The potential barrier is numerically constructed in the well-established double-folding model for both Coulomb and nuclear potentials. A realistic M3Y interaction, based on the G-matrix elements of the Paris NN potential, has been used in the folding calculation. The local approximation for the nondiagonal one-body density matrix in the calculation of the exchange potential was included by using the harmonic oscillator representation of the nondiagonal density matrix of the α particle. The computed partial half-lives and branching ratios are compared with the recent experimental data and they are in good agreement.
