L012400100010 METHOD (ACTIV) Cross section for (g,2n) was obtained by L012400100011 determining the 17F beta+ activity as a function of L012400100012 the bremsstrahlung maximum energy L012400100013 DETECTOR (NAICR) The sample activity was measured by counting L012400100014 the positron annihilation radiation with a 7.6 cm x L012400100015 7.6 cm NaI(Tl) detector L012400100016 SAMPLE Samples containing approximately 65 g of lithium L012400100017 fluoride (99.9 % purity) were prepared by pressing theL012400100018 powder into cylindrical pellets 3.2 cm in diamater andL012400100019 5 cm in length L012400100020 MONITOR Total bremsstrahlung energy in the incident beam was L012400100021 measured using a P2 ionization chamber of NBS design.
