C231100100009 INC-SOURCE The proton flux is high (10**14 protons/cm2 sec). C231100100010 SAMPLE Because of the thickness of the radium deposit C231100100011 (about 0.5 mg/cm2) and the overlapping gold, the C231100100012 fission fragments emitted at oblique angles to the C231100100013 foil normal could not escape from the target. C231100100014 DETECTOR (GEMUC) C231100100015 METHOD (CHSEP,ACTIV) After bombardment the catcher foil was C231100100016 dissolved in an acid or basic solution containing C231100100017 carrier amounts, usually 10 mg, of the fission C231100100018 product elements to be separated. The type of solvent C231100100019 used depended on the elements to be separated. Each C231100100020 sample was counted in one of a set of four end-window C231100100021 G-M counters with nearly identical shelf assemblies. C231100100022 ANALYSIS (DECAY) The decay curves were plotted and analyzed in C231100100023 the usual way, and saturation counting rates were C231100100024 determined for each radioactive species. C231100100025 ERR-ANALYS (DATA-ERR) The tabulated errors are the standard C231100100026 deviations of separate measurements.
