摘要：
The results of the Doppler-shift attenuation method lifetime measurements in partner bands of Cs-128 and La-132 are presented. Experimental reduced transition probabilities in Cs-128 are compared with theoretical calculations done in the frame of the core-quasiparticle coupling model. The electromagnetic properties, energy and spin of levels belonging to the partner bands show that Cs-128 is the best known example revealing the chiral symmetry breaking phenomenon.
