✦ Synopsis

more than 20 times when superfluid helium flows through narrow channels 7 and other impurities which are normally present as solid suspensions in liquid helium to the extent of"-0.003% 8 are simultaneously removed. According to our estimates, the concentration of He 3 in the gaseous He 4 obtained is ~< 5 x 10"6%, while the chemical purity of the gas is mainly determined by the degassing of the volumes used for its storage.
