FACILITY (CCW,2JPNJAE) JAERI FNS facility. Deuterons accelerated2208900100017
to 330 keV. The beam current was 1.5 mA. 2208900100018
INC-SOURCE (D-T) Water cooled Ti-T target. Neutron yield at 2208900100019

METHOD (ACTIV) 2208900100024
DETECTOR (GELI) 5 GeLi detectors were used. Two of these served 2208900100025
as standard detectors, and the absolute efficiency of 2208900100026
these were determined with standard gamma-ray sources.2208900100027

neutrons between 13.3 to 15.0 MeV. Determined relative2208900100030
to MONIT1. Used as neutron flux monitor. 2208900100031
Was used as a substandard for half-lives longer than 2208900100032
30 min while the reaction 13-Al-27(n,p)12-Mg-27 was 2208900100033
employed for the short-lived activities. 2208900100034
((MONIT3)13-AL-27(N,P)12-MG-27,,SIG) As substandard. 2208900100035

SAMPLE Separated isotopes were used. If the sample was 2208900100054
powder, it (about 50.mg weight) was wrapped in a 2208900100055
cartridge paper with effective area of 1 cm2. 2208900100056
Samples were positioned at a distance of 10 cm from the2208900100057
target, in the angular interval 0 - 165 degrees, thus 2208900100058
covering the energy range 13.3 - 15.0 MeV. 2208900100059
Samples with short-lived activities were transported 2208900100060
along the pneumatic tube with a transfer time of 2208900100061
about 1 sec. 2208900100062
Two Nb foils of 10.mm x 10.mm x 0.1 mm for one 2208900100063
sample - for neutron flux monitoring. 2208900100064
CORRECTION Corrections were applied for count loss due to 2208900100065
summation of cascade gammas, self-absorption in the 2208900100066
samples, fluctuation of the neutron flux during 2208900100067
irradiation, and for contribution of low energy 2208900100068
neutrons to the reaction rate. 2208900100069
