摘　　要：The level lifetimes in partner bands of 130Cs have been measured using the Doppler Shift Attenuation method （DSAM）. The high-spin states of 130Cs were populated via fusion evap- oration 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 indeed manifest chiral properties.The level lifetimes in partner bands of 130Cs have been measured using the Doppler Shift Attenuation method （DSAM）.
