The lifetimes of the excited states belonging to chiral partner bands built on πh11/2⊗νh11/2−1 configuration in 126Cs have been measured using DSA technique. For first time large set experimental transition probabilities is qualitative agreement with all selection rules predicted for strong symmetry breaking limit. originate from two general features a nucleus, namely, existence well separated left- and right-handed systems three angular momentum vectors extra symmetries appearing addition breaking.
