C250100100010 SAMPLE The target consisted of 238U or 232Th powder (10 mu-m C250100100011 size) intimately mixed with graphite powder and C250100100012 pressed into a small block about 100 mg/cm2 thick. C250100100013 The ratio of metal-to-graphite was 4-to-1 by weight. C250100100014 METHOD (MASSP) The technique of on-line mass spectrometry C250100100015 involves placing a suitable target in the ion source C250100100016 of a mass spectrometer and bombarding the target with C250100100017 projectiles. Nuclear reaction products diffuse out of C250100100018 a graphite matrix and are ionized by surface C250100100019 ionization on a hot tantalum surface. C250100100020 CORRECTION Corrected for background, overlap from adjacent peaks C250100100021 (about 5%), saturation factor, loss due to radioactiveC250100100022 decay, and loss due to diffusion of Kr precursors.
