Author(s): A. Leviatan, N. Gavrielov, J. E. García-Ramos, and P. Van Isacker The cadmium isotopes have been a classic testing ground for vibrational models of atomic nuclei with various multiphonon states identified. However, intruder states arising from the promotion of two protons across the Z = 50 shell gap are also present at low energy. Most models have trouble accounting for all the experimental data. The present paper takes a unique approach to obtain improved agreement with an extensive data set for 110 Cd, by including proton excitations in the phonon basis and exploiting a partial dynamical symmetry that mixes only certain classes of normal states.
