πg9/2⊗vh11/2doublet bands in A ∼ 100 mass region

Using the model with one particle and one hole coupled with a triaxial rotor, the πg9/2−1 ⊗vh11/2 doublet bands in the A ~ 100 mass region are studied, and compared with the πh11/2−1 ⊗vh11/2 doublet bands. It is found that the calculated results for the configuration of πg9/2−1 ⊗vh11/2 are very similar the results for a pure h11/2 proton particle and a neutron quasiparticle with λn = 5. After including the pair correlation, the model describes the candidate chiral doublet bands in 106Rh successfully, which supports the interpretation of chirality geometry.
