C229500100010 SAMPLE (96-CM-244,ENR=0.95) Samples of curium consisting C229500100011 mostly of Cm244 (95%) and containing smaller quantitiesC229500100012 of heavier curium isotopes. C229500100013 METHOD (CHSEP,REC,ACTIV) The product nuclei recoiling from C229500100014 the target were collected on thin gold foils. These C229500100015 foils were dissolved and the bulk of the fission- C229500100016 product and induced activity was removed by a C229500100017 combination of solvent-extraction and ion-exchange C229500100018 techniques. The actinide fraction could then be C229500100019 examined immediately in the alpha pulse-height C229500100020 analyzer. C229500100021 ERR-ANALYS (DATA-ERR) No details on sources of uncertainties.
