Abstract

High-spin states of In114 were populated using the reaction Pd110(Li7, 3n)In114 at a beam energy of 26 MeV. More than 30 new γ transitions and 20 new levels are identified in In114. In total, three new bands and a short cascade are observed, among which a new negative-parity ΔI=2 band built on the πg9/2-2d5/2⊗ - νh11/2 configuration before the backbend and the πg9/2-2d5/2⊗ - νh11/23 configuration after the backbend is established. The properties of this band are discussed based on the classical particle-rotor model calculations. The predicted B(E2) and ℓ(2)/B(E2) ratios indicate that the ΔI=2 band after the backbend, has the characteristics of antimagnetic rotation. Meanwhile, the two-shears-like mechanism for the possible antimagnetic rotational band is examined by investigating the orientation of the angular momenta. A new positive-parity ΔI=1 band with the configuration of πg9/2-1⊗ - ν(g7/2/d5/2)h11/22 is observed.
