Doubly magic Hs
Superheavy elements owe their existence exclusively to nuclear shell effects which stabilize them against spontaneous fission (SF). Theoretical predictions locate the center of stability at the hypothetical doubly-magic spherical nucleus with Z=114 and N=184 [1]. Calculations with the inclusion of higher orders of deformation [2] suggest the ground state shell correction energy of deformed nucl...
متن کاملDoubly Magic Nickel
N uclear physicists could easily pass for magicians. They often talk about magic nuclei as if they were about to pull these objects out of a hat and show their fuzzy long ears. This funny qualifier was coined by Eugene Wigner, who believed nuclei behave like uniform liquid droplets, but had to admit the experimental evidence pointed out by Maria Goeppert-Mayer that nuclei with neutron (N) or pr...
متن کامل"Doubly magic" conditions in magic-wavelength trapping of ultracold alkali-metal atoms.
In experiments with trapped atoms, atomic energy levels are shifted by the trapping optical and magnetic fields. Regardless of this strong perturbation, precision spectroscopy may be still carried out using specially crafted, "magic" trapping fields. Finding these conditions for particularly valuable microwave transitions in alkali-metal atoms has so far remained an open challenge. Here I demon...
متن کاملDoubly Magic Optical Trapping for Cs Atom Hyperfine Clock Transitions.
We analyze doubly magic trapping of Cs hyperfine transitions including previously neglected contributions from the ground state hyperpolarizability and the interaction of the laser light and a static magnetic field. Extensive numerical searches do not reveal any doubly magic trapping conditions for any pair of hyperfine states. However, including the hyperpolarizability reveals light intensity ...
متن کاملHigh-spin States in and around Doubly-magic Nuclei
The study of high-spin states in regions of doubly-magic nuclei performed with the use of deep-inelastic heavy ion reactions is reviewed. New and tentative results concerning high-spin states in the Ca and yrast structures in Ca, K, Ca and Sc isotopes are presented. The status of the high-spin state study in the region of Sn and Pb is outlined, including discussion of recently obtained results ...
