Possible antimagnetic rotational band in ¹¹⁴In

High-spin states of In-114 were populated using the reaction Pd-110 (Li-7, 3n)In-114 at a beam energy of 26 MeV. More than 30 new gamma transitions and 20 new levels are identified in In-114. In total, three new bands and a short cascade are observed, among which a new negative-parity AI = 2 band built on the g-2 (9/2)d(5/2) (R) vh(11/2) (3) configuration before the backbend and the g(-2) (9/2)d(5/2) (R) vhu/2 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 (2)/B(E2) ratios indicate that the AI = 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 AI = 1 band with the configuration of &pi g(-1) 9/2 (R) v(g(7/2)/d(5/2))h(iota 1/2)(2) is observed.
