  Peripheral nucleon-nucleon scattering is analysed in the framework of an
effective field theory. Distorted-wave methods are used to remove the effects
of one-pion exchange. Two-pion exchange and recoil corrections to one-pion
exchange are then subtracted pertubatively. This removes all contributions up
to order Q^3 in the chiral expansion. We have applied this to the 1D2, 1F3 and
1G4 waves, using phase shifts from various partial-wave analyses by the
Nijmegen group. In regions where these analyses agree we find no evidence for a
breakdown of the chiral expansion. One of the terms in the effective
short-range potential, the leading one in the 1D2 channel, is larger might be
expected, but in general these terms have momentum scales of about 300-400 MeV.
We also see hints of isospin breaking in the pi-N couplings.
