The process exhibits radiation zeros, i.e. configurations of the final-state particles for which the scattering amplitude vanishes. We study these zeros for both e+u and e+d scattering. The latter exhibits a type of zero which to our knowledge has not previously been identified. The observability of radiation zeros at HERA is discussed.
