INC-SOURCE (RA-BE) A 100 mc Ra-alpha-Be neutron source was placed 3127600100010
at the centre of an aluminium sphere which was filled 3127600100011
with paraffin wax. The radius of the sphere was 10-30 3127600100012
cm which corresponds to the optimum thermal neutron 3127600100013
output from a paraffin wax moderator 3127600100014
INC-SPECT Thermal spectrum. 3127600100015
SAMPLE Precise B-10 abundance in sample is unknown. 3127600100016
Three different concentrations of the boric acid 3127600100017
solution (1.254,1.481 and 1.675 g/100 c.c of solution)3127600100018
METHOD (TRN) Spherical transmission method 3127600100019
DETECTOR The outcoming neutrons were detected by an indium foil 3127600100020
of thickness 110 g/cm2. The indium foil was activated 3127600100021
for nearly five half-lives of 116In, and the induced 3127600100022
activity was followed for 1.5 hrs. The counting rate 3127600100023
was extrapolated to zero time. Initial activity due 3127600100024
to thermal neutrons only was obtained by the cadmium 3127600100025
difference technique. 3127600100026
