INC-SOURCE (SPALL) Pulsed neutron source, PEARL (Pressure and 2334000100012
Engineering Advanced Research Line) beamline. 2334000100013
METHOD (TRN) Several runs of 5-6 hours. 2334000100014
Absolute stability of each monitor, taken separately, 2334000100015
was checked to be of the order of 2% on a 24-hour 2334000100016
timescale; relative stability - ~0.2 %. 2334000100017
Temperature stability within 0.2 K. 2334000100018
The background was measured for both experimental 2334000100019
configurations (empty and filled cell). 2334000100020
SAMPLE Liquid molecular para-hydrogen in Al alloy contailer 2334000100021
of 55mm diameter, 2.5 mm thickness, fixed to a copper 2334000100022
thermal reservoir. Inside the scattering cell, out of 2334000100023
the neutron path, a solid catalyst Cr(2)O(3)- Al(2)O(3)2334000100024
was inserted to increase the rate of conversion from 2334000100025
ortho- to para-hydrogen. T=16.0 K , the pressure 2334000100026
0.3 bar. Estimated composition of 99.96% of 2334000100027
para-hydrogen. Sample thickness 2.66 mm . 2334000100028
Two vanadium thin foils before and after sample - 2334000100029
to monitor the neutron beam. 2334000100030
DETECTOR (GLASD) Li glass scintillators equipped with the 2334000100031
photomultipliers. Placed into boron-carbide-based resin2334000100032
(10 cm thickness, crispy mix) in an Al box. 2334000100033
ANALYSIS CS was calculated by the formula (1) in the ref. 2334000100034
CORRECTION The effect of the V on the sample was smaller than 2334000100035
10**-4. 2334000100036
