    For the first time the emission of neutron bursts in the process of high-voltage discharge in air was
    observed. Experiments were carried out at an average electric field strength of 1 MV m1 and
    discharge current of 10 kA. Two independent methods (CR-39 track detectors and plastic scintillation
    detectors) registered neutrons within the range from thermal energies up to energies above 10 MeV and
    with an average flux density of *106 cm2 per shot inside the discharge zone. Neutron generation occurs
    at the initial phase of the discharge and correlates with x-ray generation. The data obtained allow us to
    assume that during the discharge fast neutrons are mainly produced.
