Nuclear gamma-ray emission from antiproton annihilation at rest in uranium

Abstract

We have observed low energy nuclear gamma-rays, which we interpret as coming from fission fragments, from antiproton annihilation at rest in a uranium target. The high gamma-ray and previously reported fission neutron temperatures, as well as large relative neutron-to-gamma ray yields, suggest a high level of excitation of the fission fragments.
