Lifetime measurements and low-lying structure in

The low-lying structure of 112Sn has been studied. γ-ray excitation functions, ranging from 2.5 to 4.0MeV, and angular distributions at 2.9 and 3.8MeV have been measured following the (n,n′γ) reaction to characterize the decays of the excited levels. Level lifetimes have been measured with the Doppler-shift attenuation method. Low-lying 1-, (2-), 3- and, 5- states have been identified as members of the heterogeneous quadrupole-octupole quintuplet. Decay properties and excitation energies are consistent with the structure formed by the coupling of the lowest quadrupole, 21 +, and octupole, 31 -, excitations
