DETECTOR (IOCH) Ionization chamber filled with Ar with 4077400100013
0.03-0.1 % oxygen and 0.2-0.3 % nitrogen. 4077400100014
19-channel pulse-height analyzer. 4077400100015
Cd sheets of 0.5 mm thickness to protect from thermal 4077400100016
neutrons. 4077400100017

REACTION (3-LI-6(N,T)2-HE-4,,SIG) 4077400200003
SAMPLE Li6F layers of 0.12-0.32 mg/cm2 thickness (+-5%) were 4077400200004
deposited by vacuum evaporation on Au foil of 4077400200005
0.2 mg/cm2 thickness . The sample shape - square of 4077400200006
6.5 x 6.5 cm with rounded corners. 4077400200007
ANALYSIS Mean value of 12 measurements. 4077400200008
CORRECTION For the gaps between analyzer channels, 4077400200009
for particle absorption in the layer, 4077400200010
for backgrounds of neutrons from d-d reaction. 4077400200011
Degradation of the beam by the front wall and the 4077400200012
electrodes of the chamber ( 1-7 %) are compensated by 4077400200013
neutron scattering in the sample, hence the correction 4077400200014
for scattering was not introduced. 4077400200015
ERR-ANALYS (ERR-S) Statistical - 2.% 4077400200016
