O046900100019 METHOD (STTA) Each stack contained Uranium Target and AluminumO046900100020 foils served as recoil catchers and monitors of the O046900100021 Proton Beam intensity. O046900100022 (ACTIV) Depending upon the Products studied, O046900100023 irradiations lasted from five minutes to a few hours. O046900100024 (CHSEP) O046900100025 (INTB) Irradiations were performed in the Circulating O046900100026 Beam of Brookhaven Cosmotron.
