Hamiltonian with Broken Supersymmetry for the Xenon Isotopes

摘要

A Hamiltonian with broken u(6/2j+1) supersymmetry is proposed that can describe collective excitations in nuclei with high spin, single j orbitals. Its bosonic part is identical with IBA, while the fermionic degrees of freedom are characterized by the seniority quantum number. Groundstate as well as excited energies of eight xenon isotopes with both odd and and even mass are fairly well described by the SO(6) limit of this Hamiltonian with only one set of parameters.
