With dielectric-constant gas thermometry (DCGT) a sudden change in the low-temperature properties of gaseous 4 He has been observed. Below 3.3 K, the usual real-gas behavior ends. The change can be explained by the assumption of clustering 4He atoms. Such clusters influence the molar polarizability and the dielectric virial coefficients. This causes wrong thermodynamic temperature results of DCGT with 4He. Consistency checks with 3He revealed the best experimental value for the polarizability of 3He up to now and confirmed the feasibility of DCGT in the treated temperature range.
