Description
Symmetry and its breaking are of great importance in physics and pervade every area of nature. The interplay between these symmetries is fundamental and of significance. As a many-body quantum system with the wealth of information on symmetries, the atomic nucleus is an ideal laboratory to study the fundamental symmetries breaking and their interplay. The present work provides the first test for chirality in the A ≈ 80 mass region by lifetime measurements, and firstly elucidates the formation of chiral geometry in the presence of the octupole correlations in Br isotopes, leading to the conclusion that the reflection symmetry breaking catalyzes rather than destroys chiral symmetry breaking in nuclear systems.
