Scientific paper

Based on 1-m ESO telescope observations of Comet Halley obtained over March 10-16 and April 4-11, 1986, cometary ions and their kinematical behavior are studied to elucidate the cometary nucleus chemical composition. A strong signal at the wavelength of CO2(+) and a regular pattern of ion streamers (missing from the continuum picture) are noted. A neutral gas coma is visible in the CO(+) and N2(+) pictures (attributed to C3 and CH, respectively).
