  Exclusive photodisintegration of the deuteron in the 1-4GeV range is
described in terms of a simple covariant and gauge invariant approach using an
effective counting rule as the hard part of the d-np vertex.
  At a scattering angle of theta_cm=90 degrees a prescaling behavior of the
differential cross section proportional to 1/s^(n-2) with n ~ 12 is obtained;
going away from 90 degrees the value of n decreases slowly, in qualitative
agreement with the recent data.
