Symmetry-conserving higher-order interaction terms in the interacting boson model

Symmetry-conserving higher-order interaction terms in the interacting boson model

Symmetry-conserving higher-order terms for the interacting boson model are constructed. Their eigenvalues are explicitly derived within the SU(3) limit. The influence of these interaction terms on the theoretical energy spectrum of several nuclei is discussed. The classical limit of these operators...

Zusammenfassung:Symmetry-conserving higher-order terms for the interacting boson model are constructed. Their eigenvalues are explicitly derived within the SU(3) limit. The influence of these interaction terms on the theoretical energy spectrum of several nuclei is discussed. The classical limit of these operators is derived and interpreted.
