Description
An analysis is conducted of the March 9, 1986 distribution of the NH 336-nm band and the NH2 bands in the 580-700 nm region on Comet Halley. Of all candidates considered, only ammonia suggests itself as a parent of both NH2 and NH. The ammonia production rate is obtained from measurements of NH2 bands by dividing the observed Q(NH2) by 0.92, which is the yield of NH2 in NH3 photolysis. The NH3 presently measured is an order of magnitude lower than that derived from the Giotto IMS data. 28 refs
