We obtained intense superradiance on the 1" bands of nitrogen (λ=3914 and λ=4278 A) by using a double-pulsed transverse discharge in an He-N2 mixture at a pressure higher than 10 atm. The emission spectrum of the 2+ system (λ=3371 A) at a pressure higher than 4 atm consists of one vibrational-rotational component.
