C112300100009 INSTITUTE (1USAPUR) C112300100010 FACILITY (CYCLO,1USAANL) The Argonne National Laboratory 152 cm C112300100011 cyclotron. C112300100012 METHOD (ACTIV,EXTB) The irradiations had a duration of 3-4 h C112300100013 at a current of approximately 0.2 microA. Before each C112300100014 bombardment an alignment experiment was performed to C112300100015 insure that the beam passed through the center of the C112300100016 target and catcher foils. The catcher foil had a C112300100017 diameter of 10 cm and was cut into 10 concentric C112300100018 rings of equal width by a die and press. The angular C112300100019 interval subtended by each ring was determined by the C112300100020 target to catcher distance and the intervals were C112300100021 usually in the range from 2-3 degrees. Cerium was C112300100022 radiochemically separated from each ring. C112300100023 DETECTOR (NAICR) NaI(Tl) detectors C112300100024 ANALYSIS (DECAY) The data were analyzed by means of a C112300100025 least-squares computer program. C112300100026 ERR-ANALYS The error bars in the figures indicate the magnitude C112300100027 of all random errors in the experiments. The errors C112300100028 for the ground state product are much larger than for C112300100029 the isomer because of the mode of decay. C112300100030 (ERR-S) Random errors at low energies typically C112300100031 average about 10%. At the higher energies the C112300100032 uncertainty in the results is somewhat larger than 10%.C112300100033 (ERR-1,,5.) There is an error of less than 5% in the C112300100034 gravimetric chemical yields. C112300100035 COMMENT Compiler comment: According to the ENSDF database C112300100036 137Ce ground state T1/2=9.0 HR and isomeric state C112300100037 T1/2=34.4 HR. Authors give it the other way according C112300100038 to the assignment of 1970.
