✦ Synopsis

In order to investigate the possibility of observing the crossover of the nucleation process from the classical to the quantum regime, the decomposition of supersaturated 3He-4He mixtures in the dilute phase has been studied in the temperature range from 160 mK down to 400 IxK. The observed amount of critical supersaturation becomes almost independent of temperature below about 10 mK, while it increases with temperature above about 10 inK. The data are analyzed with the recent theory of Burmistrov, Dubovskii and Tsymbalenko. The results indicate a crossover temperature around 70 mK and the existence of the effect of dissipation.

In order to avoid possible sources of heat leaks into liquid 3He-4He mixtures we have constructed an experimental setup using only materlals of high purity. The inner part of an Ag-cell was furnished with a 700~-Ag sinter (A = llOm 2) and two vlbratlng wires. The temperature of the cell wall was mea
