Deep inelastic reactions and isomers in neutron-rich nuclei across the perimeter of the A = 180-190 deformed region

Recent results on high-spin isomers populated in deep-inelastic reactions in the transitional tungsten-osmium region are outlined with a focus on Os-190, Os-192 and Os-194. As well as the characterization of several two-quasinutron isomers, the 12(+) and 20(+) isomers in Os-192 are interpreted as manifestations of maximal rotation alignment within the neutron i(13/2) and possibly proton k(11/2) shells at oblate deformation.
