چکیده
New transitions in neutron-rich $^{100}\mathrm{Y}$ have been identified a $^{9}\mathrm{Be}+^{238}\mathrm{U}$ experiment with mass and $Z$ gates to provide full fragment identification. These high spin levels of investigated by analyzing the statistics $\ensuremath{\gamma}\text{\ensuremath{-}}\ensuremath{\gamma}\text{\ensuremath{-}}\ensuremath{\gamma}$ $\ensuremath{\gamma}\text{\ensuremath{-}}\ensuremath{\gamma}\text{\ensuremath{-}}\ensuremath{\gamma}\text{\ensuremath{-}}\ensuremath{\gamma}$ coincidence data from spontaneous fission $^{252}\mathrm{Cf}$ at Gammasphere detector array. Two new bands, 14 levels, 23 identified. The ${K}^{\ensuremath{\pi}}={4}^{+}$ band decaying $1s$ isomeric state is assigned be high-$K$ Gallagher-Moszkowski (GM) partner known ${K}^{\ensuremath{\pi}}={1}^{+}$ band, $\ensuremath{\pi}5/2[522]\ensuremath{\bigotimes}\ensuremath{\nu}3/2[411]$ configuration. This ${4}^{+}$ also proposed pseudospin ${K}^{\ensuremath{\pi}}={5}^{+}$ ${5}^{+}\phantom{\rule{4pt}{0ex}}\ensuremath{\pi}5/2[422]\ensuremath{\bigotimes}\ensuremath{\nu}5/2[413]$ configuration, form $\ensuremath{\pi}5/2[422]\ensuremath{\bigotimes}\ensuremath{\nu}[312\phantom{\rule{4pt}{0ex}}5/2,3/2]$ neutron doublet. Constrained triaxial covariant density-functional theory quantal particle rotor model calculations applied interpret structure available electromagnetic transition probabilities are found good agreement experimental values.

Evidence for multiple chiral doublet bands in 133Ce.
Two distinct sets of chiral-partner bands have been identified in the nucleus 133Ce. They constitute a multiple chiral doublet, a phenomenon predicted by relativistic mean field (RMF) calculations and observed experimentally here for the first time. The properties of these chiral bands are in good agreement with results of calculations based on a combination of the constrained triaxial RMF theo...
متن کاملPseudospin, Spin, and Coulomb Dirac-symmetries: Doublet Structure and Supersymmetric Patterns
The Dirac equation serves as the basis for the relativistic description of atoms, nuclei and hadrons. In atoms the relevant potentials felt by the electron are Coulombic vector potentials. A Dirac Hamiltonian with a Coulomb potential exhibits a finestructure spectrum with characteristic two-fold degeneracy. Relativistic mean fields in nuclei generated by meson exchanges , and quark confinement ...
متن کاملDoublet craters on Venus
Of the impact craters on Earth larger than 20 km in diameter, 10–15% (3 out of 28) are doublets, having been formed by the simultaneous impact of two well-separated projectiles. The most likely scenario for their formation is the impact of well-separated binary asteroids. If a population of binary asteroids is capable of striking the Earth, it should also be able to hit the other terrestrial pl...
