Abstract：
The recently observed two high-spin rotational bands in the proton emitter ¹¹³Cs are investigated using the cranked shell model with pairing correlations treated by a particle-number conserving method, in which the Pauli blocking effects are taken into account exactly. By using the configuration assignments of band 1[π3/2⁺[422](g_7/2), α=-1/2] and band 2[π1/2⁺[420](d_5/2), α=1/2], the experimental moments of inertia and quasiparticle alignments can be reproduced much better by the present calculations than those using the configuration assginment of π1/2^-[550](h_11/2), which in turn may support these configuration assignments. Furthermore, by analyzing the occupation probability n_μ of each cranked Nilsson level near the Fermi surface and the contribution of each orbital to the angular momentum alignments, the backbending mechanism of these two bands is also investigated.
