TL;DR: In this article, the nuclear mass formula was used to study heavy and superheavy nuclei, and the potential energy surface for fission was calculated by the same method as used for obtaining the shell energies.
Abstract: The nuclear mass formula which was recently constructed by the author and his collaborators is used to study heavy and superheavy nuclei. The most distinctive characteristic of this formula is that the shell energy of a deformed nucleus is expressed as an appropriate mixture of spherical shell energies added to an average deformation energy. This mass formula gives ground-state masses and shapes of nuclei ranging from light nuclei (Z⩾2,N⩾2) to superheavy nuclei. In the region of superheavy nuclei, the shell energies of this mass formula show a few magic numbers, which are not so pronounced as in 132Sn and 208Pb. The α-decay Q-values are calculated, and the α-decay half-lives are estimated with use of a phenomenological formula. These results are compared with experimental data and other predictions. The potential energy surface for fission can be calculated by the same method as used for obtaining the shell energies. Based on these energy surfaces, the spontaneous fission is discussed for some selected su...

TL;DR: In this article, the relationship between the mass of charged particles and zero-point electromagnetic fields is revisited, and a simple model comprising a scalar field coupled to stochastic or thermal electromagnetic fields are introduced.
Abstract: Motivated by recent works on the origin of inertial mass, we revisit the relationship between the mass of charged particles and zero-point electromagnetic fields. To this end we first introduce a simple model comprising a scalar field coupled to stochastic or thermal electromagnetic fields. Then we check if it is possible to start from a zero bare mass in the renormalization process and express the finite physical mass in terms of a cut-off. In scalar QED this is indeed possible, except for the problem that all conceivable cut-offs correspond to very large masses. For spin-1/2 particles (QED with fermions) the relation between bare mass and renormalized mass is compatible with the observed electron mass and with a finite cut-off, but only if the bare mass is not zero; for any value of the cut-off the radiative correction is very small.

TL;DR: In this paper, a quadratic mass formula proposed by Talmi for identical nucleons in an open and non degenerate shell is discussed and corrections coming from the breaking of generalized seniority are examined.
