The Δ I = 2 bands in 109 In: possible antimagnetic rotation

The high-spin structure of 109 In was investigated with the 100 Mo ( 14 N , 5n ) 109 In fusion-evaporation reaction at CIAE, Beijing. Eleven new γ -rays of 109 In were identified, by which the bandheads of the Δ I = 2 rotational bands were confirmed. The configurations were assigned with the help of the systematic discussion. Furthermore, the rotational bands are compared with the tilted-axis cranking calculations based on a relativistic mean-field approach. The rotational bands involving the 1 p 1 h excitation to the π d 5 / 2 and π g 7 / 2 orbitals
