SAMPLE     Targets of U-233, U-235, U-238 and Np-237. Usually     C255900100012 
           uranium metal foils about 0.002 in. thick were used    C255900100013 
           as targets. They were covered with pure Al foils       C255900100014 
           which acted as catcher foils for the fission           C255900100015 
           products. In most experiments only the catcher foils   C255900100016 
           were used for preparing the samples, enabling          C255900100017 
           repeated use of the valuable fissionable foils. By     C255900100018 
           bombarding a blank aluminum foil alone it was shown    C255900100019 
           that no disturbing activity was produced in the        C255900100020 
           catcher foils.                                         C255900100021

METHOD     (CHSEP,ACTIV,COINC) The chemical separation of cesium  C255900100023 
           was done essentially by two consecutive ironhydroxide  C255900100024 
           precipitations preceded and followed by                C255900100025 
           precipitations of cesium as cesium-perchlorate.        C255900100026 
           Initially, the gamma-spectrum was measured with a 3    C255900100027 
           in. by 3 in. NaI(T1) crystal with conventional         C255900100028 
           electronics and a 200-channel pulse height analyzer.   C255900100029 
           Aluminum absorbers of appropriate thickness            C255900100030 
           prevented beta-particles from entering the crystal.    C255900100031 
           At a later stage of the work, Compton anticoincidence  C255900100032 
           counting equipment became available. Two 4 in. x 4     C255900100033 
           in. NaI(TI) crystals facing each other and having the  C255900100034 
           sample between them were surrounded by a large         C255900100035 
           plastic scintillator. Moreover any gamma-ray which is  C255900100036 
           in coincidence with another one was counted with       C255900100037 
           reduced efficiency since the second gamma ray in the   C255900100038 
           cascade could also produce anticoincidence pulses in   C255900100039 
           the surrounding plastic scintillator.                  C255900100040 
CORRECTION A correction was applied for gamma-absorption in the   C255900100041 
           aluminum beta-absorbers.                               C255900100042
