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.
