        <p>В работе приведены результаты трехмерного PIC-моделирования эксперимента по генерации сильноточных узконаправленных релятивистских электронов при взаимодействии лазерного импульса петаваттного класса с мишенью из пены с околокритической плотностью электронов. Ширина углового распределения вылетевших электронов, характерная температура спектра ускоренных электронов и их количество хорошо согласуются с данными, полученными в~эксперименте.</p>

        <p>The paper presents the results of a three-dimensional PIC simulation of an experiment on the generation of high-current narrowly directed relativistic electrons when a petawatt-class laser pulse interacts with a target made of foam with a near-critical electron density. The width of the angular distribution of the ejected electrons, as well as the characteristic temperature of the accelerated electron spectrum, are in good agreement with the data obtained in the experiment</p>
