“…Different from the cluster model, also some other theoretical models have been proposed in the pursuit of a microscopic description of α decay, such as the shell model and the fission-like model [26][27][28][29].…”

Based on the recent data in NUBASE2012, an improved empirical formula for evaluating the α-decay half-lives is presented, in which the hindrance effect resulted from the change of the ground state spins and parities of parent and daughter nuclei is included, together with a new correction factor for nuclei near the shell closures. The calculated α-decay half-lives are found to be in better agreements with the experimental data, and the corresponding root-mean-square (rms) deviation is reduced to 0.433 when the experimental Q-values are employed. Furthermore, the Q-values derived from different nuclear mass models are used to predict α-decay half-lives with this improved formula. It is found that the calculated half-lives are very sensitive to the Q-values. Remarkably, when mass predictions are improved with the radial basis function (RBF), the resulting rms deviations can be significantly reduced. With the mass prediction from the latest version of Weizsäcker-Skyrme (WS4) model, the rms deviation of α-decay half-lives with respect to the known data falls to 0.697.

“…Very recently, two-proton emission from an unbound ground state has been observed in the three-body decay of 12 O [3]. The mass and excited states of the long searched heavy helium isotope 10 He (which has the largest observed neutron to proton ratio) has been measured [4,5] using a beam where both the projectile and the target are radioactive nuclei.…”

“…Further details of the present calculation and a discussion on the choice of the basis set used in the CSHF approach will be published elsewhere. We will apply the CSHF method to calculate the widths of the ground state of the nuclei 10 He, 12 O, 26 O and 28 O. The parameters of effective nucleon-nucleon interactions are fitted to reproduce properties of selected stable nuclei as well as nuclear and neutron matters.…”

A microscopic calculation of α-cluster preformation probability and α decay width in the typical α emitter 212 Po is presented. Results are obtained by improving a recent approach to describe α preformation in 212 Po [Phys. Rev. C 90, 034304 (2014)] implementing four-nucleon correlations (quartetting). Using the actually measured density distribution of the 208 Pb core, the calculated alpha decay width of 212 Po agrees fairly well with the measured one.
