Abstract
A two-Q-phonon mixed-symmetry J(pi) = 2(2,ms)(+), state was identified in t he nucleus (MO)-M-94. This identification is based on lifetime information for the first nine 2(+) states. The proton-neutron version of the interacti ng boson model (IBM-2) suggests the interpretation of the 2(6)(+) state of Mo-94 as a two-Q-phonon 2(2,ms)(+ state) Recent microscopic calculations su pport this interpretation.
