    "abstract": "If a beam of unpolarized positrons (which is considered as a sum of two\nfractions with opposite helicities) passes through an intense circular\npolarized laser radiation these fractions may be separated. For high laser\nflash intensity each positron will interact with $k_0\\gg$1 laser photons\nsubsequently (linear multiple compton scattering process). Due to difference in\nthe compton cross-section for positrons polarized in opposite directions the\nmean final energy of each fraction will be different. It allows to get a\npolarized positron beam using the momentum selection (with some intensity\nloss). Estimations show the possibility to obtain a positron beam with 35%\nlongitudinal polarization and 25% intensity from the initial one for focussed\nlaser flash with total energy 5J and positron beam with energy 5 GeV.",
