Abstract:
A rotational band of 16γ-rays has been found in131Ce with a high moment of inertia indicating a deformation ε2~0.38 and extending to spin ~40?. Its intensity is ~~5% of the total in131Ce, confirming a difference in the intensity systematics for superdeformed states in Ce nuclei compared with Nd.
