摘要：
The origin of the strong CO Cameron band emission in the Red Rectangle is investigated. From a comparison of laboratory spectroscopic data and astronomical observations in combination with chemical modelling, it is concluded that the Cameron band emission of CO originates from the dissociative recombination of HCO+, and its intensity provides a measure of the product of the density of HCO+ ions and the electron density, integrated along the line of sight.
