Abstract
Studies devoted to the discovery and investigation of chiral-symmetry breaking in nuclei are briefly reviewed. Unlike the case of molecules and the macrocosm, where chirality manifests itself in the spatial structure of objects, chirality in nuclei is connected with different relative orientation of valence-quasiparticle spins and the angular momentum of collective rotation of the triaxial core. Decisive arguments in favor of the existence of this effect are based on measurements of lifetimes of high-spin nuclear levels in the picosecond range by Doppler methods of γ spectroscopy.
