TL;DR: In this paper, the mass, α-decay and spontaneous fission half-life of superheavy elements were studied in macroscopic-microscopic approaches with two different macro-scopic models and the delta-pairing interaction.
Abstract: Masses, α-decay and spontaneous fission half-lives of superheavy elements are studied in macroscopic-microscopic approaches with two different macroscopic models and the delta-pairing interaction. Model mass deviations obtained with different formulae are 0.5-0.8MeV.

TL;DR: In this paper, the Morse-type potential was derived from the GMO mass formula and its modified accurate mass formula, and some simple mass formulas were obtained, from this they predicted some masses of unknown hadrons.
Abstract: The base is the Lagrangian of symmetry and its dynamical breaking or Higgs breaking. When the soliton-like solutions of the scalar field equations are substituted into the spinor field equations, in the approximation of non-relativity we derive the Morse-type potential, whose energy spectrum is the GMO mass formula and its modified accurate mass formula. According to the symmetry of s-c quarks, the heavy flavor hadrons which made of u,d and c quarks may be classified by SU(3) octet and decuplet. Then some simple mass formulas are obtained, from this we predict some masses of unknown hadrons.

TL;DR: In this paper, the authors used a combination of improved shell model and deformation corrections to the liquid-drop mass law to calculate fission barrier heights and fission Q-values.
Abstract: Development within the past decade of improved shell model and deformation corrections to the liquid-drop mass law has not only improved its accuracy but also allowed use in more aspects of nuclear physics, such as calculation of fission barriers. Additional experimental data are thus available as input for determination of mass-formula parameters. Preliminary results including fission barrier heights and fission Q-values as input data will be presented. Statistical tests have been performed on fits to the 1971 mass table and to the input reactions and doublets, indicating a possible discrepancy between the two forms of data.

TL;DR: In this article, an analytic expression for the total energy of 4He clusters composed of N atoms is obtained by means of a variational solution of the energy density functional, which is calculated as an expansion in decreasing powers of the cluster radius, R∝N1/3.
Abstract: An analytic expression for the total energy of 4He clusters composed of N atoms is obtained by means of a variational solution of the energy density functional. The energy is calculated as an expansion in decreasing powers of the cluster radius, R∝N1/3. Contributions of volume (R3), surface (R2), curvature (R), constant (R0), (1/R), and (1/R2) are clearly separated in the formula. Chemical potentials, fusion and fission potentials, surface thickness, and unit radii are also obtained.
