摘　　要：The level states of the nucleus ^(124)Cs have been populated through the ^(116)Sn(^(11) B,3n)reaction at a beam energy of 45MeV,provided by the HI-13 tandem accelerator of the China Institute of Atomic Energy.A number of low-lying states are constructed.The level states in theπh_(11/2)νg_(7/2) side band are extended down to lower spin by one h.The level energies and spins in the rotational bands are determined through the establishment of various connections,which confirm the spin assignment of the yrast band in ^(124)Cs based on excitation energy systematics.It is revealed that with the present spin assignment,theπh_(11/2)νg_(7/2) side band shows signature inversion at low-spin region and the inversion occurs at a spin of about 16h.
