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.
