M026300100009 INC-SOURCE (QMPH,TAGD)) M026300100010 METHOD (EXTB,SITA) The method of tagged-photons was used. M026300100011 SAMPLE The scattering target was 7.4 g/cm-sq powder M026300100012 of U-O(3), packed in a thin-walled Lucite container. M026300100013 DETECTOR (MAGSP) Post-Bremsstrahlung electrons were analysed M026300100014 in a magnetic spectrometer. M026300100015 (NAICR) Post-Bremsstrahlung electrons were detected M026300100016 in coincidence with the associated photon. M026300100017 ERR-ANALYS (ERR-S) Statistical errors only.
