✦ Synopsis


The temperature dependence of the mobility of positive ions in 3He at a pressure of 60 Torr has been studied from 0.7 to < 0.08 K ; an unusually sharp peak is observed at approximately 0.2 K.

The contribution to the specific heat due to order parameter fluctuations in liquid SHe just above the super)quid transition temperature Tc is calculated exactly within a Landau theory approach. The effect turns out to be unobservably small and thus cannot explain the large (-9 %) rise in specific h
