High- K isomers in neutron-rich zirconium isotopes.

The neutron-rich zirconium isotopes are a key testing ground for nuclear models due to their sensitivity to shape changes, and because they cross the r-process path of explosive nucleosynthesis. Furthermore, recent experimental data have revealed a high-spin isomer in l08Zr. Here we report the results of configuration-constrained potential-energy-surface calculations of ground states and high-K states in 104-110Zr, restricted to quadrupole and hexadecapole shapes. These calculations enable the existing isomer data to be understood, and predictions are made for 110Zr. [ABSTRACT FROM AUTHOR]
