C242500100009 cyclotron. C242500100010 SAMPLE Approximately 100 mg of 235U foil (~50 mg/cm2), C242500100011 surrounded by very pure one mil aluminum catcher foils.C242500100012 DETECTOR (NAICR) A Harshaw Integral Line Assembly 3 in. x 3 in. C242500100013 NaI(T1) crystal. C242500100014 METHOD (CHSEP,ACTIV) A 235U foil, was bombarded by 10 MeV C242500100015 protons for two hours using the University of C242500100016 Washington 60-in. cyclotron with an average proton C242500100017 current of 35 microA. Several min after the end of C242500100018 bombardment the catcher foils were dissolved in 3 ml C242500100019 of concentrated HCL. The 0.77 MeV gamma rays from the C242500100020 35 day 95Nb were counted. The decay of the 90 hr C242500100021 95mNb isomer was observed by detection of the Nb K C242500100022 X-ray accompanying the nearly 100 per cent internal C242500100023 conversion decay mode of this 0.234 MeV level. C242500100024 CORRECTION A correction was made for the growth of the 65 day 95ZrC242500100025 into 95Nb during and after bombardment before the firstC242500100026 chemical separation. The correction due to 95Zr decay C242500100027 was 25 per cent of the total activity. In evaluating C242500100028 the absolute efficiency for the detection of the C242500100029 isomeric state corrections were made for the C242500100030 fluorescence yield (0.72), conversion in higher shells C242500100031 (K/[K + L + M]= 0.79), absorption in the detector C242500100032 window, and self-absorption in the sample itself.
