The decay of high-spin states in the continuum of {sup 130}Ce is studied via {gamma}-ray and internal conversion electron spectroscopy. An electron surplus above predicted yields based on {gamma} data is seen in coincidence with transitions in the yrast band of {sup 130}Ce. We attribute this to an admixture of electric monopole ({ital E}0) transitions with unstretched {ital E}2 and {ital M}1 transitions between strongly interacting bands of different deformations in the continuum. The {ital E}0 matrix elements needed to explain this surplus are comparable in magnitude to reported {ital E}0 matrix elements between discrete states in neighboring nuclei. {copyright} {ital 1996 The American Physical Society.}
