The possible chiral doublet structures in 104Rh with the asymmetric configuration πrg-19/2⊕vh11/2 have been studied in the triaxial particle-rotor model. The spectra, the Ⅰ - ω relations and the transition probabilities support the existence of the chiral bands in this nucleus. The γ-deformation interval -35°≤γ≤-25°for appearance of chiral doublets in 104Rh is given. With appropriate moment of inertia and the configuration πrg-19/2⊕vh11/2, the experimental spectra in 104 Rh, 106Rh, 108Rh, 110Ag have been well reproduced by the yrast bands of the triaxial particle-rotor-model calculation.
