Chirality of Nuclear Rotation

It is shown that the rotating mean field of triaxial nuclei can break the chiral symmetry. Two nearly degenerate DeltaI=1 rotational bands originate from the left-handed and right-handed solutions.

Hybrid version of the tilted axis cranking model and its application to128Ba

A hybrid version the deformed nuclear potential is suggested, which combines a spherical Woods Saxon potential with a deformed Nilsson potential. It removes the problems of the conventional Nilsson potential in the mass 130 region. Based on the hybrid potential, tilted axis cranking calculations are carried out for the magnetic dipole band in ^{128}Ba.

CHIRALITY OF ROTATING NUCLEI

The orientation of the angular momentum vector with respect to the triaxial density distribution selects a left-handed or right-handed system principal axes. This breaking of chiral symmetry manifests itself as pairs of nearly identical ∆I = 1bands. The chiral structures combine high-j particles and high-j holes with a triaxial rotor. Tilted axis cranking calculations predict the existence of such configurations in different mass regions.

Left‐Handed Nuclei

The orientation of the angular momentum vector with respect to the triaxial density distribution selects a left‐handed or right‐handed system principal axes. This breaking of chiral symmetry manifests itself as pairs of nearly identical ΔI = 1‐bands. The chiral structures combine high‐j particles and high‐j holes with a triaxial rotor. Tilted axis cranking calculations predict the existence of such configurations in different mass regions. There is experimental evidence in odd‐odd nuclei around mass 134. The quantized motion of the angular momentum vector between the left‐ and right‐handed configurations, which causes the splitting between the chiral sister bands, can be classified as tunneling (chiral rotors) or oscillation (chiral vibrators).
