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
A L L M/3ssbauer experiments at low temperatures published so far have been performed in cryostats in which liquid He 4 is the ultimate cooling agent. An early exception was the investigation of nuclear polarization of Co 5v in iron by Taylor l and his colleagues down to 0.35Β°K in a He 3 refrigerato
