g factor of chiral doublets with π(1h_11/2)¹ ⊗ ν(1h_11/2)⁻¹ configuration. II. Pairing effect

The pairing effects on the g factor of chiral doublets in the π(1h₁₁/₂)¹ ⊗ ν(1h₁₁/₂)⁻¹ configuration are investigated using the particle rotor model. The results show that the g factors of yrast and yrare bands decrease with increasing neutron pairing gap Δ_n. At the bandhead (I = 9h̄), the g factor is decreasing for the yrast state and increasing for the yrare state as the triaxial deformation parameter γ increases. The g factor varies with spin I based on γ: for γ < 30^◦, it increases then decreases; for γ > 30^◦, it decreases then increases. A kink in the yrast band’s g factor may signal aplanar rotation. These trends are linked to the proton (j_p), neutron (j_n), and total (I) angular momenta and their effective angles θ_pI and θ_nI. An increase in the short (long) axis component of I reduces θ_pI (θ_nI), increasing (decreasing) the g factor with spin. Moreover, the θ_nI is reduced by Δ_n and results in smaller g factor.
