Journal ArticleDOI
Nuclear ground state masses and deformations
TL;DR: In this paper, the atomic mass excesses and nuclear ground-state deformations of 8979 nuclei ranging from 16O to A = 339 were tabulated based on the finite-range droplet macroscopic model and the folded-Yukawa single-particle microscopic model.
Journal ArticleDOI
Nucleus-nucleus proximity potential and superheavy nuclei
W.D. Myers,W.J. Swiatecki +1 more
TL;DR: In this paper, the authors used up-to-date values of nuclear radii and of the nuclear surface tension to compare the 1977 proximity treatment of nucleus-nucleus interaction with 113 measured fusion barriers.
Journal ArticleDOI
Nuclear mass formula with a finite-range droplet model and a folded-Yukawa single-particle potential
TL;DR: In this article, the error of a mass formula is defined in a rigorous way, which leads naturally to the use of experimental uncertainties and of the maximum-likelihood method to derive a set of equations for estimating the parameters and error of the theoretical model.
Journal ArticleDOI
Fusion by diffusion. II. Synthesis of transfermium elements in cold fusion reactions
TL;DR: In this article, a method of estimating cross sections for the synthesis of very heavy nuclei by the fusion of two lighter ones is described, where the cross section is considered to be the product of three factors: the cross-section for the projectile to overcome the Coulomb barrier, the probability that the resulting composite nucleus reaches the compound nucleus configuration by a shape fluctuation treated as a diffusion of probability in one dimension, and the probability of the excited compound nucleus survives fission.

TL;DR: In this paper, three decay chains were observed, each consisting of an implanted heavy atom and six subsequent $\ensuremath{\alpha}$ decays, correlated in time and position, indicating the decay of a new high- $Z$ element.
