Nuclear isomers: structures and applications
Isomeric states in the nuclei along the rapid proton capture process path are studied by the projected shell model. Emphasis is given to two waiting point nuclei 68Se and 72Kr that are characterized by shape coexistence. Energy surface calculations indicate that the ground state of these nuclei corresponds to an oblate-deformed minimum, while the lowest state at the prolatedeformed minimum can ...
متن کاملUps and Downs of Nuclear Isomers
ergy? That tantalizing question reflects a dream that some have hoped to realize by exploiting the energy-storage capabilities of nuclear isomers. But the hope hinges on facets of nuclear behavior that remain unknown despite decades of study. Electromagnetic transitions and b decay, the basic mechanisms that largely determine isomer halflives, are well understood. In many cases, however, it is ...
متن کاملControlled Extraction of Energy from Nuclear Isomers
The Army must deploy increasingly powerful energy sources to support sustained operations anytime and anywhere in the world. Excited states of nuclei can store 5 orders of magnitude more energy than that stored in chemical bonds. Conventional nuclear storage systems such as radioisotopes cannot be turned on when the energy is required. This paper describes a switchable nuclear battery that may ...
متن کاملNuclear isomers: stepping stones to the unknown
The utility of isomers for exploring the nuclear landscape is discussed, including their role in superheavy-element research, and the possibility of observing neutron radioactivity. Emphasis is given to K isomers in deformed nuclei. Transition rates are examined in the NpNn scheme for 2and 3-quasiparticle K-isomer decays, and in connection with level densities for higher quasiparticle numbers.
متن کاملLight - induced conversion of nuclear spin isomers of molecules
We report on a new phenomenon of molecular nuclear spin isomers conversion in the field of resonant laser radiation. It is based on the isomer-selective optical excitation and the difference of conversion rates for excited and unexcited molecules. We expect the considerable magnitude of the effect for all molecules which absorb the radiation of existing lasers. In a recent work [1] a phenomenon...
