Abstract
A t1/2>1 ms, high-K isomeric state feeding a strongly coupled rotational band has been identified following the deep inelastic reaction $^{238}_{\phantom{1}92}$U + $^{186}_{\phantom{1}74}$W at 1600 MeV. Examination of ${\gamma}$-ray and X-ray data combined with a g-factor analysis derived from in-band branching ratios suggests the assignment of the new states to the neutron-rich nucleus $^{185}_{\phantom{1}73}$Ta.
