Summary

The rotating mean field in triaxial nuclei breaks chiral symmetry, leading to two distinct rotational bands. These bands, originating from left-handed and right-handed solutions, offer new insights into nuclear structure.

Area of Science:

  • Nuclear Physics
  • Quantum Mechanics

Background:

  • Triaxial nuclei exhibit complex rotational behavior.
  • Chiral symmetry breaking is a key phenomenon in nuclear structure.

Purpose of the Study:

  • To investigate the impact of rotating mean fields on chiral symmetry in triaxial nuclei.
  • To identify the emergence of distinct rotational bands due to symmetry breaking.

Main Methods:

  • Theoretical modeling of rotating mean fields in triaxial nuclei.
  • Analysis of nuclear rotational bands and their properties.

Main Results:

  • Demonstrated that the rotating mean field can break chiral symmetry in triaxial nuclei.
  • Observed the formation of two nearly degenerate rotational bands (DeltaI=1).
  • These bands correspond to left-handed and right-handed chiral solutions.

Conclusions:

  • The rotating mean field is crucial for understanding chiral symmetry breaking in nuclei.
  • The identified rotational bands provide experimental signatures for chiral symmetry breaking.
