We tabulate the atomic mass excesses and nuclear ground-state deformations of 8979 nuclei ranging from O to A = 339. The calculations are based on the finite-range droplet macroscopic model and the folded-Yukawa single-particle microscopic model. Relative to our 1981 mass table the current results are obtained with an improved macroscopic model, an improved(More)
We tabulate the ground-state odd-proton and odd-neutron spins and parities, proton and neutron pairing gaps, total binding energy, one-and two-neutron separation energies, quantities related to-delayed one-and two-neutron emission probabilities ,-decay energy release and half-life with respect to Gamow-Teller decay, one-and two-proton separation energies,(More)
The role of temporal fluctuations and systematic variations of interaural parameters in localization of sound sources in spatially distributed, nonstationary noise conditions was investigated. For this, Bayesian estimation was applied to interaural parameters calculated with physiologically plausible time and frequency resolution. Probability density(More)
Fusion barriers are calculated in a macroscopic-microscopic model for several cold-fusion heavy-ion reactions leading to heavy and superheavy elements. The results obtained in such a picture are very diierent from those obtained in a purely macroscopic model. For reactions on 208 Pb targets, shell eeects in the entrance channel result in fusion-barrier(More)
Realistic fusion barriers are calculated in a macroscopic-microscopic model for several soft-fusion heavy-ion reactions leading to heavy and superheavy elements. The results obtained in such a realistic picture are very different from those obtained in a purely macroscopic model. For reactions on Pb targets, shell effects in the entrance channel result in(More)
On the basis of a nine-parameter expanding source model that includes special relativity, quantum statistics, resonance decays, and freeze-out on a realistic hypersurface in spacetime, we analyze in detail invariant π+, π, K+, and K one-particle multiplicity distributions and π+ and K+ two-particle correlations in nearly central collisions of Si + Au at(More)
A detailed understanding of complete fusion cross sections in heavyion collisions requires a consideration of the effects of the deformation of the projectile and target. Our aim here is to show that deformation and orientation of the colliding nuclei have a very significant effect on the fusion-barrier height and on the compactness of the touching(More)
We discuss recent developments in macroscopic-microscopic mass models, including the 1992 finite-range droplet model, the 1992 extended-ThomasFermi Strutinsky-integral model, and the 1994 Thomas-Fermi model, with particular emphasis on how well they extrapolate to new regions of nuclei. We also address what recent developments in macroscopic-microscopic(More)
