accuracy of + 0.10e. The width of the resonance curve for which it is still possible to measure the shift on the oscilloscope screen should not be more than ~120 Oe. 1 The accuracy in measuring the magnetrostriction con-2 stants by the method described is ~3%. The sensitivity in striction is 10-8.
The design of a continuous flow helium cryostat is described for optical studies with an optical fixed high-pressure chamber in the temperature range from 4 to 300 K. The liquid helium consumption for 4 K is 21 h-', and less than 0.5 1 h-'for temperatures above 20 K.
The bomb works very reliably and, ignoring a certain residual deformation of the windows, none of its components, including the windows, has ever failed. A simple method has thus been developed for studying optical and photoelectric properties at high pressures at temperatures of 220-230Β°K (the phas
