FACILITY (VDG,2ZZZGEL) CN-type Van de Graaff accelerator 2210800100012
at GEEL. About 40 - 50 micro-amps of deuterons were 2210800100013
accelerated to 3 MeV. 2210800100014
INC-SOURCE (D-T) Neutrons in the energy range 12.5 to 19.6 MeV 2210800100015
were produced with an absorbed titanium-tritium target2210800100016
by using 15 different emerging angles. The tritium 2210800100017
target was a 3 mg/cm2 T-Ti layer on a 4 cm diameter by2210800100018
0.3 mm thick silver sheet, cooled by a thin water 2210800100019
film. 2210800100020
INC-SPECT .The neutron spectrum effective at each sample was cal-2210800100021
culated using a MONTE-CARLO code based on the kine- 2210800100022
matics of the T(D,N) reaction. 2210800100023
METHOD (ACTIV) Activation technique in combination with high- 2210800100024
resolution gamma-ray spectroscopy was used to measure 2210800100025
the activity from the Y-90m, Nb-92m, Cs-136 and Hf-1812210800100026
products, as well as the Na-24 monitor activity. 2210800100027
(CHSEP) The Y-90g product was radiochemically separated2210800100028
and the beta- activity was counted. 2210800100029
DETECTOR (GELI) A 35 cm3 Ge(Li) detector was used for the gamma 2210800100030
measurements, while beta-ray counting was employed for2210800100031
the beta emitter Y-90g. The latter measurement was 2210800100032
started about 30 hours after the end of the 2210800100033
irradiation, in order to have complete decay of Y-90m.2210800100034
(TELES) A proton recoil telescope, placed at an angle 2210800100035
of 16 degrees and a distance of 80 cm from the neutron2210800100036
source was used to measure the neutron fluence. 2210800100037
MONITOR (13-AL-27(N,A)11-NA-24,,SIG) Activation. 2210800100038
(1-H-1(N,EL)1-H-1,,SIG) Proton recoil telescope. 2210800100039
.A weighted average of these two fluence monitors was 2210800100040
used. The values agreed in general within 5 percent. 2210800100041
DECAY-MON (11-NA-24,14.96HR,DG,1368.,1.) 2210800100042
SAMPLE .The samples consisted of 2 cm diameter by 0.5 cm thick2210800100043
discs of metal or oxide powder, pressed at a pressure 2210800100044
of 18 tons/cm2. The purities were for Nb g.t. 99.5 2210800100045
percent, for Ta g.t. 99.7 percent, while the La sample2210800100046
was the compound La2O3 of technical quality. The 2210800100047
samples were sandwiched between two aluminium sheets, 2210800100048
2 cm in diameter by 0.1 cm thick. The distance from 2210800100049
the source to the sample middle plane was 7.8 cm. 2210800100050
Irradiations were performed for 40 to 67 hours. 2210800100051
CORRECTION .The gamma count rates were corrected for self-absorp- 2210800100052
tion, pile up, coincidence loss, geometry, efficiency 2210800100053
of the detector and gamma-ray abundance. The beta 2210800100054
count rates were corrected for chemical yield, absorp-2210800100055
tion in the counter window, finite-size geometry and 2210800100056
efficiency of the detector. 2210800100057
