Evidence of coexistence of chiral, electric, magnetic, and anti-magnetic rotations as well as noncollective structure
Low-, medium-, and high-spin states in 119 Sb were populated using the reaction 116 Cd( 7 Li, 4n) at beam energies of 34, 42, and 50 MeV, respectively. A pair of nearly degenerate Δ I = 1 doublet, two Δ I = 1 , and two Δ I = 2 bands as well as a number of irregular levels have been observed. These structures are interpreted as chiral, electric, magnetic, and anti-magnetic rotations as well as noncollective structure, which is supported by three-dimensional tilted axis cranking and triaxial multi-quasiparticle rotor model calculations. This is the first example of coexistence of chiral, electric, magnetic, and anti-magnetic rotations as well as noncollective structure in one single nucleus.
