Neutron Magic Number

In this work, we systematically study the [Formula: see text] decay half-lives of 170 even–even nuclei with [Formula: see text] within the two-potential approach while the [Formula: see text] decay preformation factor [Formula: see text] is obtained by the cluster-formation model. The calculated results can well reproduce the experimental data. In addition, we extend this model to predict the [Formula: see text] decay half-lives of 64 even–even nuclei with [Formula: see text] whose [Formula: see text] decay is energetically allowed or observed but not yet quantified. For comparison, the two famous models i.e., SemFIS proposed by Poenaru et al. [Europhys. Lett. 77 (2007) 62001] and UDL proposed by Qi et al. [Phys. Rev. Lett. 103 (2009) 072501] are used. The predicted results of these models are basically consistent. At the same time, through analyzing the changing trend of [Formula: see text] decay energy [Formula: see text] of [Formula: see text] and 128 isotopes nuclei with the increasing of neutron number N and that of [Formula: see text] decay preformation factor [Formula: see text] of those isotopes even–even nuclei with the increasing of neutron number N, [Formula: see text] may be a new neutron magic number.

The nuclei in the [Formula: see text] [Formula: see text] and [Formula: see text] regions, lying on both sides of the [Formula: see text]-stability line, continue to be of interest for their complex nuclear structures. The Grodzins product rule (GPR) viz. [Formula: see text], for the ground bands of even-[Formula: see text] even-[Formula: see text] nuclei provides a useful approach to study these structures. The utility of our method, displaying the linear relation of [Formula: see text] to [Formula: see text], is illustrated for the [Formula: see text] Zn to [Formula: see text] Cd series of isotopes. The spread of the data on the linear plots enables a quick view of the shape phase transitions. The role of the shells and the subshells, at spherical and deformed shell gaps for neutrons and protons, with their mutual re-inforcement and the shape phase transition are vividly visible on our plots. The development of collectivity in this region is also linked to the effective number of valence nucleons above the magic number of [Formula: see text], and 28 rather than [Formula: see text], for Mo to Cd isotopes for a microscopic calculation.

New Formula

The phenomenological formula for ground state binding energy derived earlier [G. Gangopadhyay, Int. J. Mod. Phys. E 20 (2011) 179] has been modified. The parameters have been obtained by fitting the latest available tabulation of experimental values. The major modifications include a new term for pairing and introduction of a new neutron magic number at N = 160. The new formula reduced the root mean square deviation to 363[Formula: see text]keV, a substantial improvement over the previous version of the formula.
