Neutron bursts associated with lightning cloud-to-ground discharges

Abstract

We consider bursts in the neutrons registered by the Yakut spectrograph of cosmic rays and the electrostatic fluxmeter (± 50 kV/m). Bursts were observed during a significant change in the field, which changes abruptly from − 16 kV/m to 18 kV/m during negative lightning. It was found that during the positive lightning have not been observed bursts of neutrons, despite that the electric field changes abruptly from 10 kV/m up to −30 kV/m during the lightning discharge.
