      <abstract xml:lang="ru">
        <p>Работа посвящена разработке аналитической теории для расчета пространственного распределения энерговыделения при распространении пучка быстрых электронов в газе (в частности, в воздухе) с учетом неупругого взаимодействия. Рассматриваются энергии электронов 1-100 кэВ. На основании анализа данных о сечениях упругого и неупругого взаимодействия электронов с молекулами газов, содержащихся в воздухе, делается вывод о том, что неупругое взаимодействие, в основном, приводит к релаксации энергии, а упругое – к релаксации импульса. При решении кинетического уравнения Больцмана для электронов используется модельное сечение неупругих столкновений электронов с молекулами, которое обеспечивает хорошее описание экспериментально найденной энергетической зависимости массовой тормозной способности электронов. Полученные результаты для зависимости средней энергии электронов от числа неупругих столкновений находятся в хорошем соответствии с расчетами по методу разложения функции распределения по числам столкновений и решению аналогичной задачи методом Монте-Карло.</p>

        <p>This work is dedicated to the formulation of an analytical theory for calculating the spacial distribution of energy release in a fast electron beam moving in gas and, particularly, in air, considering inelastic interaction. Electron energies of 1-100 keV are considered. Based on the analysis of data on the cross sections for inelastic and elastic interaction of electrons with gas molecules contained in air, it is concluded that inelastic collisions mainly cause energy relaxation, and elastic collisions cause mostly impulse relaxation. Solving Boltzmann’s kinetic equation for the electrons, it is used a model cross-section for the inelastic collisions of electrons with molecules, which guarantees a good description of the measured energy dependence of the mass stopping power of the electrons. Obtained results for de dependence of electrons´ mean energy on the number of inelastic collisions are in good compliance with the results obtained with the method of expanding distribution function in collision numbers and also with the results of Monte-Carlo simulation.</p>
