Coexistence and B(E2)'s in 42Ca

New data have just appeared for Coulomb excitation of 42Ca, providing E2 transition matrix elements connecting several low-lying states. I have applied a simple two-state mixing model to the lowest two 0+, 2+, and 4+ states in order to fit the experimental matrix elements. Results indicate that the 0+ and 4+ states are nearly pure, whereas the 2+ states are strongly mixed. My excited band is found to be about 3.6 times more collective than the ground band.
