- 1) Energetic protons don't "see" the nuclei. the result is that the nucleus is
- a collection of protons and neutrons. Add the events up and thjat is what you g
- et.
-
- 2) proton-nucleus interactions are low momentum events which have low cross-sec
- tion
-
- 3) You can tell the difference from the momentum profile. of the event. Large P
- t events are the signature.
