20 Jan 2011 | | Abstract: | Shell model calculations reveal that the low-lying spectrum of the $N=Z$
nucleus $^{92}_{46}$Pd is generated from a correlated isoscalar spin-aligned
neutron-proton pair mode, exhibiting a new form of collectivity different from
vibrational and rotational excitations. Already the ground state structure of
$^{92}$Pd is mostly built from isoscalar pairs each carrying angular momentum
$J=9$. This structure is different from all other even-even nuclei studied so
far. The energy spectrum generated by the correlated neutron-proton pairs has
two distinctive features: i) it is almost equidistant for low-lying energies
and ii) the transition probability $I
ightarrow I-2$ is approximately constant
and independent of $I$. This exotic coupling scheme is predicted to correspond
to the yrast structures of the heaviest nuclei approaching the doubly-magic
$^{100}$Sn. | | Source: | arXiv, 1101.4046 | | Services: | Forum | Review | PDF | Favorites | |
