In the Fermilab Accumulator an experimentally observed "neutral flux" was observed. Presumably the flux is originating from a distribution of trapped ions in the antiproton beam. In P. Zhou's dissertation work it was suggested that some ion escape mechanisms could be the root source of the "neutral flux". The two escape mechanisms suggested are charge exchange and recombination. The purpose of this work is to experimentally determine the nature of the "neutral flux". Using a detector that can detect ultraviolet light, it can be determined to what extent recombination photons contribute to the "neutral flux". This work was unable to observe a significant ultraviolet photon flux, thereby suggesting the "neutral flux" is primarily neutral particles.
