INC-SOURCE (AM-BE)20 Ci 241Am-Be isotopic neutron source, 3171600100011
moderated with water. 3171600100012
SAMPLE (23-V-51,NAT=0.9975) 10 ppm standard solution of 3171600100013
vanadium, and the comparator isotope Mn-55 as also 3171600100014
contained in a 10 ppm standard solution of manganese. 3171600100015
The certified concentration of manganese in the 3171600100016
manganese standard solution was 10.01 +/- 0.03 mg/g 3171600100017
and that of vanadium was 4.86 +/- 0.02 mg/g in the 3171600100018
vanadium standard solution. 3171600100019
INC-SPECT The extent of non-ideality of epithermal flux shape, 3171600100020
alpha-factor at the sample irradiation position was 3171600100021
experimentally determined to be 0.134 +/- 0.01 by 3171600100022
dual monitor method using 197Au and 95Zr. The thermal 3171600100023
neutron flux is (1.46+/-0.01)x10**4 n/cm**2/s and the 3171600100024
epithermal neutron flux is 3171600100025
(7.23+/-0.02)x10**2 n/cm**2/s. 3171600100026
DETECTOR (HPGE) Induced radioactivity in the samples were 3171600100027
counted by HPGe coaxial detector, which has a 3171600100028
relative efficiency of 25%. 3171600100029
