Abstract
The decay of high-spin states in the continuum of Ce-130 is studied vi a gamma-ray and internal conversion electron spectroscopy. An electron surplus above predicted yields based on gamma data is seen in coincid ence with transitions in the yrast band of Ce-130. We attribute this t o an admixture of electric monopole (EO) transitions with unstretched E2 and M1 transitions between strongly interacting bands of different deformations in the continuum. The EO matrix elements needed to explai n this surplus are comparable in magnitude to reported EO matrix eleme nts between discrete states in neighboring nuclei.
