Abstract
In a phase-shift analysis of all Pp scattering data below MeV, where / ( is number of degrees of freedom) is reached, the long- and intermediate-range pp interaction has been studied. Using as intermediate-range interaction the Nijmegen potential, we find for the pp coupling constant =(72.5±0.6)× or =13.1±0.1 and for the mass 134.7±2.1 MeV. Even when we take account of the model dependence due to the potential tail, this value of is significantly lower than the value of the charged coupling constant in πN scattering, indicating a large breaking of charge independence.
