Partial dynamical symmetry in Bose-Fermi systems
Résumé
We generalize the notion of partial dynamical symmetry (PDS) to a system of interacting bosons
and fermions. In a PDS, selected states of the Hamiltonian are solvable and preserve the symmetry exactly, while other states are mixed.
As a first example of such novel symmetry construction, spectral features of the odd-mass nucleus $^{195}$Pt are analyzed.
