About the possibility to measure the circular polarization of high-energy photon in reaction γ + e⁻ → e⁺ + e⁻ + e⁻
Two possibilities of the measuring high-energy photon circular polarization by means of the process γ + e⁻ → e⁺ + e⁻ + e⁻ are investigated. The first one is connected with the measurement of polarization asymmetry of the cross section when the initial electron beam is longitudinally polarized. The s...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Two possibilities of the measuring high-energy photon circular polarization by means of the process γ + e⁻ → e⁺ + e⁻ + e⁻ are investigated. The first one is connected with the measurement of polarization asymmetry of the cross section when the initial electron beam is longitudinally polarized. The second possibility related with the measurement of the created-positron (or electron) polarization. Just this polarization does not decrease when the photon energy grows up and can be used for effective determination of the photon circular polarization degree. |
