Tidal effects and the Proximity decay of nuclei

Abstract

We examine the decay of the 3.03 MeV state of ${}^8$Be evaporated from an excited projectile-like fragment following a peripheral heavy-ion collision. The relative energy of the daughter $\alpha$ particles exhibits a dependence on the decay angle of the ${}^8$Be${}^{\ast }$, indicative of a tidal effect. Comparison of the measured tidal effect with a purely Coulomb model suggests the influence of a measurable nuclear proximity interaction.
