Annihilation of Low-Energy Antiprotons in Nuclei

摘要

We discuss the effect of antiproton annihilation within nuclei from the perspective of realistic intranuclear cascade calculations (INC). The results indicate a significant energy deposition for a class of annihilations that are shown to occur relatively deep within the nucleus. In addition, promising experimental observables and triggers are identified. The calculations are especially relevant to LEAR antiproton-nucleus experiments, particularly PS 187. This experiment is described here and possible future investigations are suggested. (ERA citation 07:060377)
