Abstract
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.
