Balmer series seri-ye Bâlmer (#) Fr.: série de Balmer A series of hydrogen → Historically, Balmer emission lines (mainly Hα) from ionized nebulae were first observed by O. Struve and C. T. Elvey (1938, ApJ 88, 364). This was an important indication of the existence of hydrogen, in the ionized state, in the → interstellar medium. |
