Based on the excitation space anisotropy a partial polarisation of the spontaneous emission is found in hollow cathode discharge. This polarisation is ascribed to existing spontaneous coherence, i. e., self-alignment of the excited states. The aligning factors are the beam-like fast electrons from the cathode dark space. An expression for observed signal of the spontaneous emission magnetic depolarisation is obtained. Withim the frames of the ordinary opto-galvanic effect a separate coherent conductivity is analysed. a poor coherent conductivity due the self-aligned states is detected.
