Photonuclear data from the same experiment. C255900100009
INSTITUTE (1USAANL,2AUSIRK) C255900100010
FACILITY (CYCLO,1USAANL) The Argonne 60 in. cyclotron. C255900100011
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
DETECTOR (NAICR,SCIN) Two 3 in. x 3 in. NaI(T1) crystals. C255900100022
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
