Abstract：
The level lifetimes in partner bands of ¹³⁰Cs have been measured using the Doppler Shift Attenuation method. The high-spin states of ¹³⁰Cs were populated via fusion evaporation reaction ¹²⁴Sn(¹¹B, 5n)¹³⁰Cs at a beam energy of 65 MeV. The absolute M1 and E2 transition probabilities have been deduced. The results indicate that the partner bands of ¹³⁰Cs manifest the chiral properties.
