The cross section for two-neutron removal from a beam of relativistic is calculated in an eikonal approximation. We find a larger nuclear cross section in reactions with heavy nuclei than estimated by Kobayashi et al. This lowers the inferred Coulomb cross section for reactions on from 890 to a range of 560–740 mb, depending on the assumed single-particle binding energy of the valence neutron.
