摘要：
The model of initial acceleration of electrons of terrestrial gamma-ray flashes with a hard spectrum is presented, according to which this acceleration occurs at screening of the electric field with the intensity of the order of 10(6) V/cm near the lateral surface of a new conductive region, arising at the formation of a new step of a negative leader of lightning after the contact of the head of a positive volume leader with the channel of the main leader. The number of electrons undergoing such acceleration during the formation of one leader step can be of the order of 10(17). (C) 2015 Elsevier B.V. All rights reserved.
