“…The comets Bradfield (1980t), Austin (1982g), Kohoutek (1973f), Crommelin (1983n), P/Encke (1984) and P/Halley (1982i) observed by Goraya et al (1982;1986a, b;, 1988, Babu (1974) and Hartley-Good (19851) observed by Rautela et al (1988) were studied in the framework of the Haser model (1957) by using our recently derived fluorescence efficiencies. For completeness, we have extended our Haser model analysis to C2 (1, 0), Cz (0, l), C2 (0,2) and C3 (0, 0,O) weak emission band fluxes observed in the coma of comet Wilson (19861) by Sanwal and Rautela (1988) using our derived g-values at rh = 1 AU as described below.…”

Emission fluxes of CN, C2 and C3 species observed in the coma of some comets are analysed in the framework of Haser model. CN, Cz and C3 production rates are determined using recently derived fluorescence efficiencies and dependence of CN, C2 and C3 production rates on the heliocentric distance is studied. Evidence for a burst type activity around January 15, 1974 in the post-perihelion period of comet Kohoutek (1973f) is observed.
