| 摘 要： | 用云南天文台一米望远镜卡焦摄谱仪(f=175mm相机),在哈雷彗星的日心距分别为1.11AU和0.83AU时,作了两次彗发光谱观测,得到了典型的彗发光谱。本文绘出了各带系清晰的分子发射光谱图及认证结果。此外,本文还给出了彗发CN的(0—1)带(λ4216)和C_3的蓝紫发射(λ4052)及C_2的(2—0)带(λ4365)的强度比CN/C_3和CN/C_2,其值分别为CN/C_3=1.03,CN/C_2=1.00。最后,我们还将结果与其他作者在这次回归中所得到的结果进行了比较。

| Abstract: | The observations of the coma of Comet Halley have been made with the 102-cm RCC telescope at the Yunnan Observatory on December 25, 1985 and January 13, 1986. The reciprocal dispersion of the first order spectrum is 29 A/mm. The nitrogenbaked Kodak plates showed a continuum with strong molecular bands in emission. The main emission bands are as follows:CN(3883.4A ,3871.4A ,3861.9A .3854.7A)CN(4216.0A)C3(4051.0A)C2(Swan band)C2(4114.5A ,4365.2A) .C2(4668.7A ,4697.6A ,4678.6A)C2(4715.2A,4737.1A)G2(5129.3A ,5165.2A ,5899.3A)The emission intensity ratios are CN/C2= 1.03, and CN/C2 = 1.00. |
