【 摘 要 】

Synopsis We have calculated the population distributions of many electronic excite states as a function of time in collisions of bare, hydrogen-like and helium-like C, N and O ions with neutral targets, H, He, and H2. Using the population distribution, we have calculated theoretical emission spectra in the collision system. Comparing the theoretical spectra with the observation, we have estimated the detection efficiency of the spectrometer and discuss the singlet-triplet ratio in charge exchange collisions of hydrogen-like ions.
