New molecular ions in spectra of comet P/HalleySpectroscopic observations (4000 to 7000 A) were obtained of comet P/Halley near the time of the spacecraft encounters in March 1986. Molecular ion emission features were observed in the long-slit CCD spectra. Additional spectroscopic observations obtained in April 1986 confirm the presence of many new ion features in the plasma tail. It is proposed that CO2(+) be identified with the new features in the 4000 to 4350 A region. The other unidentified ion features may be attributable to a single ion species.
