On the observation of the Λ-doubling in the O - O UV N2laser band

The spectral composition of the (O-O) N

UV stimulated band, as the linewidths of the individual stimulated transitions remain unchanged when the nitrogen pressure and the excitation voltage range from 40 to 100 torr and, from the threshold, to 10 kV, respectively, is observed with a laboratory superradiant emitter.
