M047900100014 SAMPLE The cloud chamber filled with He-3 gas with a M047900100015 pressure of 0.9 atm was used simultaneously as M047900100016 detector and target. M047900100017 ANALYSIS Since in the (g,p) reaction only two particles are M047900100018 emitted it is possible to determine the energy of M047900100019 the g-quantum from the emission angle and the M047900100020 momentum of only one of outgoing particles. By M047900100021 measuring both tracks the correctness of this M047900100022 identification of event can be checked. Then the M047900100023 cross section can be obtained by dividing of the M047900100024 number of events in narrow range of g-quanta M047900100025 energies by number of photons in the same range of M047900100026 bremsstrahlung spectrum. M047900100027 ERR-ANALYS (ERR-1) The systematic errors caused by intensity M047900100028 measurements are only estimated to be about of 6%.
