摘要：
Comet C/1995 01 (Hale-Bopp) was observed on 27 April 1996 with the ISOPHOT instrument of ISO when it was at 4.6 AU from the Sun. The 2.5-12 mu m spectrum was recorded at low resolution. We present here the preliminary results of this observation. The 2.5-5 mu m spectrum shows emission in the CO2 v(3) band. The CO2 production rate is about 1.3 x 10(28) s(-1). The 6-12 mu m spectrum shows thermal emission at a colour temperature of 162 K (6-8 mu m range) and a strong silicate band around 10 mu m, with a narrow feature at 11.2 mu m indicative of crystalline silicates.
