Linking transitions from the superdeformed band inEu143

Abstract

Connections between the superdeformed and normal-deformed states in ${}_{}{}^{143}{}_{}{}^{}\mathrm{Eu}$ have been established by measuring energy sums of two consecutive γ-ray transitions in the linking cascade. Six decay paths have been observed connecting discrete states in the two potential wells. The absolute excitation energy and the most likely spin of the superdeformed band have been determined directly for the first time.
