The analysis of p3He annihilation events at rest (from the PS 179 experiment at LEAR) gives the value 0.467 ± 0.035 for the ration between the annihilation cross sections on n and on p. This low value indicates a strong isospin dependence of the NN amplitude in P wave. © 1989.

Abstract
The analysis of p3He annihilation events at rest (from the PS 179 experiment at LEAR) gives the value 0.467 ± 0.035 for the ration between the annihilation cross sections on n and on p. This low value indicates a strong isospin dependence of the NN amplitude in P wave. © 1989.File in questo prodotto:
