Abstract
Coherent ${\ensuremath{\rho}}^{+}$ production on neon nuclei has been observed in charged-current events in a neutrino bubble-chamber experiment. The incident neutrino energy was 10--320 GeV, with a median event energy of 80 GeV. The rate per charged-current event was (0.28\ifmmode\pm\else\textpm\fi{}0.10)%. Comparison was made to vector-meson-dominance predictions; agreement with the overall rate, but disagreement at high neutrino energies and at high ${Q}^{2}$, was found.
