Three-state mixing among 0+ states in even Cd isotopes.

Abstract

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.
