ShareEFFECT OF MINOR HELIUM 3 IMPURITIES ON THE FIRST SOUND VELOCITY IN HELIUM II AT LOW TEMPERATURES.
[In Russian. / En russe.]
Author(s) : RUDAVSKIJ E. Ja., CAGOVEC V. K.
Type of article: Article
Summary
PRECISE RELATIVE MEASUREMENTS ARE CARRIED OUT OF THE FIRST SOUND VELOCITY IN SOLUTIONS CONTAINING 0,5, 0,155 AND 0,51% HELIUM 3 FROM 0,1 TO 0,7 K. THE HELIUM 3 CONCENTRATION IS FOUND TO CONTROL THE TEMPERATURE DEPENDENCE OF THE SOUND VELOCITY. THE VELOCITY MAXIMUM IS OBSERVED IN THE WEAKEST SOLUTIONS AND IN MORE CONCENTRATED SOLUTIONS, THE VELOCITY MONOTONICALLY DECREASES WITH RISING TEMPERATURE.
