Description:
<jats:p>The results of measurements of the thermal conductivity of pure and carbon-monoxide-doped nitrogen crystals in the temperature range 1.2–26 K are presented for samples containing up to 0.7% CO molecules. It follows from a preliminary analysis that the interaction of phonons with an admixture molecule having the same mass as the host molecule is relatively weak and depends weakly on the admixture concentration within the investigated range of carbon monoxide concentrations in the nitrogen crystal.</jats:p>
