Abstract：

In the last decade, chiral symmetry in atomic nuclei has attracted significant attention and become one of the hot topics in current nuclear physics frontiers. This paper provides a review of experimental studies for nuclear chirality in China. In particular, the experimental setups, chiral mass regions, lifetime measurements, and simultaneous breaking of chirality and other symmetries are discussed in detail. These studies found a new chiral mass region (A ≈ 80), extended the boundaries of the A ≈ 100 and 130 chiral mass regions, and tested the chiral geometry of ¹³⁰Cs, ¹⁰⁶Ag, ⁸⁰Br and ⁷⁶Br by lifetime measurements. In addition, simultaneous breaking of chirality and other symmetries have been studied in ⁷⁴As, ⁷⁶Br, ⁷⁸Br, ⁸⁰Br, ⁸¹Kr and ¹³¹Ba.

Key words： nuclear chirality lifetime measurements energy spectra electromagnetic transition probabilities
