Abstract
The thermal conductivity of HeI was measured at saturated vapor pressure from ${10}^{\ensuremath{-}7}$ \ifmmode^\circ\else\textdegree\fi{}K to 5 \ifmmode\times\else\texttimes\fi{} ${10}^{\ensuremath{-}3}$ \ifmmode^\circ\else\textdegree\fi{}K above ${T}_{\ensuremath{\lambda}}$. The results agree in detail with dynamic scaling predictions and yield a critical exponent of 0.334 \ifmmode\pm\else\textpm\fi{} 0.005. The prediction is $\frac{1}{3}$.
