Abstract

The chiral two-pion exchange component of the long-range

pp

interaction is studied in an energy-dependent partial-wave analysis. We demonstrate its presence and importance and determine the chiral parameters

c_{i}

(

i = 1, 3, 4

). The values agree well with those obtained from pion-nucleon amplitudes.
