Three-state mixing among0+states in even Cd isotopes

Ratios of (t,p) transfer intensities to $0^{+}$ states in the cadmium isotopes have been analyzed using a three-state mixing model. The data allows determination of the degree of mixing of the rotational (intruder) state into the zero-phonon and two-phonon $0^{+}$ states. The three lowest $0^{+}$ states are found to be relatively pure and the intruder state lies above the two-phonon state in the heavier isotopes.
