Abstract

The ortho-D2 concentration of gas samples taken from the liquid D₂ cold moderator of the SINQ spallation neutron source at PSI has been measured. A value of c_o=0.762±0.001(statistical)±0.006(systematical) for the in situ quasiequilibrium at a temperature of 25 K and at an almost continuous power deposition of 230±50 mW/g is established for samples taken after long irradiation periods. This unexpectedly low value, (math equation) is explained by a simple radiation-induced breakup and recombination model for D2 molecules.
