Abstract

We examine the decay of the 3.03 MeV state of Be8 evaporated from an excited projectilelike fragment following a peripheral heavy-ion collision. The relative energy of the daughter α particles exhibits a dependence on the decay angle of the Be*8, indicative of a tidal effect. A comparison of the measured tidal effect with a model suggests a measurable nuclear proximity interaction.
