Abstract

We make a systematic calculation on α-decay branching ratios to members of ground-state rotational band and to excited $0^{+}$ states of even–even nuclei by a simple barrier penetration approach. The branching ratios to the excited states of daughter nucleus are determined by the α-decay energy, the angular momentum of α-particle, and the excitation probability of the daughter nucleus. Our calculation covers isotopic chains from Hg to Fm in the mass regions $180 < A < 202$ and $A ⩾ 224$ . The calculated branching ratios of α-transitions are consistent with the experimental data. Some useful predictions are made for future experiments.

The phenomenology of particle and cluster emission
2022, Atomic Data and Nuclear Data Tables
We review emission data for proton-, even–even $α$ - and heavy cluster (HC) radioactivity in a unified model by using a realistic analytical approach for the barrier penetration and spectroscopic factor. The realistic fragment–core nuclear interaction is approximated by a parabolic dependence which is matched to the Coulomb potential at the barrier radius. Thus, the fragment dynamics inside the barrier can be described with analytical semiclassical solutions. The centrifugal and deformation effects within the Fröman approach are investigated. We present systematics of the spectroscopic factors and give universal laws for decay widths of proton, even–even $α$ and heavy cluster emission processes. We make remarks on the main universal phenomenological features of these decays. Finally we describe the universal law for the even–even $α$ -emission fine structure.

Systematic research on α-decay rates of spherical and deformed nuclei
2015, Annals of Physics
$α$ decay is of significant interest for the study of nuclear structure and for the synthesis of new superheavy elements. Theoretical approaches in recent $α$ -decay studies are reviewed. After a brief review of the systematic laws of $α$ -decay half-lives, various expressions for the decay width are discussed together with the $α$ preformation factor. These expressions are separately derived within the semiclassical approximation, direct method, distorted wave approach, (modified) two-potential approach, and coupled-channel approach. Within the coupled-channel representation, two techniques to deal with the coupling interaction matrix are discussed for precise descriptions of the $α$ -decay fine structure. Various $α$ -decay calculations within all these different approaches are presented and compared. It is found that both semiclassical and quantum-mechanical calculations well reproduce the experimental $α$ -decay half-lives within a mean factor of about two. However, the semiclassical formalism fails in describing the $α$ transitions to high-lying members of one rotational band, while the coupled-channel approach including enough decay channels gives a precise description of the $α$ -decay fine structure observed in heavy deformed nuclei.
Systematics of the α-decay fine structure in even-even nuclei
2015, Atomic Data and Nuclear Data Tables
We describe $α$ -transitions to low-lying states in even–even nuclei with $Z > 50, N > 82$ using the Coherent State Model (CSM). We reproduce the energy levels and electromagnetic transition rates between the states of the ground band employing two parameters, namely the deformation parameter and the strength of the harmonic CSM Hamiltonian. The B(E2) values are described in terms of an effective charge which depends linearly on the deformation parameter. The treatment of the $α$ -emission process is based on an $α$ –daughter interaction containing a monopole component, calculated through a double folding procedure with a M3Y interaction plus a repulsive core simulating the Pauli principle, and a quadrupole–quadrupole (QQ) interaction. The decaying states are identified with the lowest narrow outgoing resonances obtained through the coupled channels method. The $α$ -branching ratios to $2^{+}$ states are reproduced by means of the QQ strength. This interaction strength can be fitted with a linear dependence on the deformation parameter, as predicted by the CSM. The theoretical intensities to $4^{+}$ and $6^{+}$ states are in reasonable agreement with available experimental data. Predictions are made for spherical, transitional and well deformed even–even $α$ -emitters.

The ENSDF evaluation for A=222 mass chain (1996El01) has been updated on the basis of the experimental results, since September 1995 (literature cutoff date in 1996El01), from various reaction and decay studies for all nuclides in A=222 mass chain (Z=84 to 92). A new nuclide (²²²Po) has since been observed. In addition, new measurements have been reported in Rn, Th and Ra nuclides. The results obtained from various theoretical studies are given as comments. The updated level and decay schemes, and experimental decay and reaction data on which they are based, are summarized and presented for all the nuclides with mass number A=222. The adopted values of level energies, level spins and parities are given, and γ-ray energies, intensities, as well as other nuclear properties are presented. The references, Jπ arguments, and necessary comments are given in the text. All Q values have been adopted from 2011AuZZ. Theoretical work of 2009Mo27 was consulted.
