摘要：
Radon has been known to dissolve well in water although the exact mechanism of this process is still not clear. Thus we investigate a correlation of the solubility of radon to solvent clusters. We found experimentally that the solubility decreases in ethanol-water solutions at certain ethanol contents. Calculation of the clathration enthalpies for a noble gas atom confined in (H2O)(20) clusters were performed by using a DFT method to find a correlation between the theoretical enthalpies and experimental enthalpies of dissolution. It is suggested from the results that radon is water-soluble due to encapsulation in a water cluster.
