Clarification of confusion in level scheme of ¹²⁴Cs

Low-lying and high-spin states of ¹²⁴Cs are studied through the ¹¹⁶ Sn(¹¹ B,3n)¹²⁴ Cs reaction at a beam energy of 45 MeV. Several new linking transitions are observed, including three transitions between the yrast and πh_11/2 ⊗ νd _3/2 bands and two transitions between the yrast and πh _11/2 ⊗ ν(d_5/2, g_7/2) bands. These transitions fix the excitation energy of the yrast band and its decay path, and confirm the existence of eight E1 linking transitions between the yrast and πh_11/2 ⊗ ν(d_5/2, g_7/2) bands observed before. These E1 linking transitions infer the octupole correlation in Cs. The decay paths of the yrast band are investigated, and discrepancies in the level scheme of ¹²⁴Cs in the latest two studies are clarified. The reason for the discrepancies is discussed. A new decoupled band is established and temporarily assigned as the unfavored signature partner of πh _11/2 ⊗ νd_3/2 configuration.
