At energies above the threshold for W production the process \ensuremathν\ensuremathγ\ensuremath→lW+ is competitive with \ensuremathν\ensuremathν scattering at the same center of mass energies. In a cosmological setting, absorption of ultrahigh energy neutrinos by the microwave photon background is comparable to absorption by the neutrino background. In passing through matter, the process \ensuremathν\ensuremath→lW+ will occur in the Coulomb field of nuclei. For iron, the interaction rate per nucleon is roughly 20% of the charge current cross section. The related process \ensuremathνee^\ensuremath-\ensuremath→\ensuremathγW^\ensuremath- dominates \ensuremathνee^\ensuremath- scattering for about a decade in energy above the resonance for W production.
