| Abstract | Results are presented of a survey undertaken to increase the number of active galaxies and interacting pairs with radio emission observed in the 21-cm H I line. Relatively high-shift objects, generally in the range 7000-15,000 km/s, were selected. Details of the source selection, observing technique, and results are presented, including H I data and spectra for all detected galaxies and spectra for selected nondetections. Nine of the 18 Seyfert galaxies were detected. Neutral hydrogen masses range from seven to thirty-four billion solar masses. Both M(H I) and M(H I)/L(B) are typical of values for normal late-type spirals, although some of the detected Seyferts have peculiar early morphological types. None of the 12 radio galaxies or nine interacting pairs with radio emissions was detected in H I. The upper limits are consistent with no significant excess of neutral hydrogen for the indicated morphological types. No evidence is found for a correlation between H I flux and near-IR nuclear flux density. |
