Masses and Deformations of Neutron-rich Nuclei
We have calculated the masses, deformations, and other properties of 8979 nuclei ranging from O to 136 and extending from the proton drip line to the neutron drip line on the basis of the 1992 version of the finite-range droplet model. The predicted quantities include the ground-state mass, deformation, microscopic correction, odd-proton and odd-neutron spins and parities, proton and neutron pa...
متن کاملHyperon masses in nuclear matter.
We analyze hyperon and nucleon mass shifts in nuclear matter using chiral perturbation theory. Expressions for the mass shifts that include strong interaction effects at leading order in the density are derived. Corrections to our results are suppressed by powers of the Fermi momentum divided by either the chiral symmetry breaking scale or the nucleon mass. Our work is relevant for neutron star...
متن کاملRegularity and chaos in the nuclear masses
Shell effects in atomic nuclei are a quantum mechanical manifestation of the single–particle motion of the nucleons. They are directly related to the structure and fluctuations of the single–particle spectrum. Our understanding of these fluctuations and of their connections with the regular or chaotic nature of the nucleonic motion has greatly increased in the last decades. In the first part of...
متن کاملNuclear energy density optimization: Large deformations
A new Skyrme-like energy density suitable for studies of strongly elongated nuclei has been determined in the framework of the Hartree-Fock-Bogoliubov theory using the recently developed model-based, derivative-free optimization algorithm pounders. A sensitivity analysis at the optimal solution has revealed the importance of states at large deformations in driving the parameter-ization of the f...
متن کاملOdd-Even Staggering of Nuclear Masses: Pairing
The odd-even staggering of nuclear masses was recognized in the early days of nuclear physics. Recently, a similar e ect was discovered in other nite fermion systems, such as ultrasmall metallic grains and metal clusters. It is believed that the staggering in nuclei and grains is primarily due to pairing correlations (superconductivity), while in clusters it is caused by the Jahn-Teller e ect. ...
