The Electron Energy Loss Rates by Polar Molecules ASHIHARA, Osamu Simple useful formulae are derived for rates of electron energy loss through the rotational and vibrational excitation of polar molecules. Accuracy of the these formulae is tested by comparing rates from the formulae with results of direct numerical calculations from the relevant cross sections on some molecules abundant in the cometary atmospheres. The energy loss rates, as functions of the difference between electron and gas temperatures, are presented in graphical forms for H_2O, OH, CO, CH, NH, NH_3,and also for H_2 and O for the gas temperatures : 300K, 500K and 1000K. 資料番号: SA2401207000 東京大学宇宙航空研究所 Institute of Space and Aeronautical Science,University of Tokyo 1975-06 eng departmental bulletin paper https://jaxa.repo.nii.ac.jp/records/34508 0372-1418 AA00675986 ISAS report/Institute of Space and Aeronautical Science,University of Tokyo 40 10 257 275 https://jaxa.repo.nii.ac.jp/record/34508/files/SA2401207.pdf application/pdf 943.9 kB 2020-01-24
