L022600100011 SAMPLE A 2.59-mg/cm2 Trycite polystyrene (CH2) film target L022600100012 10.3 cm high by 3.05 cm wide was placed 2.5 m from L022600100013 the internal bremsstrahlung target of an electron L022600100014 synchrotron. The target was oriented with its normal L022600100015 rotated an angle of 60 degrees from the beam axis. L022600100016 The cross section of the x-ray beam was 2.4x4.7 cm2 L022600100017 at the position of the polystyrene target. L022600100018 DETECTOR (TELES,SIBAR) Each detector telescope consisted of a L022600100019 110-microm-thick, 3-cm2-area transmission-type L022600100020 surface-barrier detector followed by a 4.5-mm-thick., L022600100021 5-cm2-area stopping detector of the lithium-drifted L022600100022 silicon type. Detectors were operated at room L022600100023 temperature. L022600100024 METHOD (EDE,COINC) The energy and angular distributions of L022600100025 photoprotons have been observed with 30.5- and L022600100026 32.1-MeV electron bremsstrahlung using the dExE L022600100027 coincidence technique.
