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.

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.

An extensive theoretical search for the proton magic number in the superheavy valley beyond Z = 82 and the corresponding neutron magic number after N = 126 is carried out. For this we scanned a wide range of elements Z = 112–130 and their isotopes. The well-established non-relativistic Skryme–Hartree–Fock and Relativistic Mean Field formalisms with various force parameters are used. Based on the calculated systematics of pairing gap, two-neutron separation energy and the shell correction energy for these nuclei, we find Z = 120 as the next proton magic and N = 172, 182/184, 208 and 258 the subsequent neutron magic numbers.
