Abstract

A pulse technique is employed to measure the ultrasonic propagation velocity in solutions of helium in liquid hydrogen in the temperature region T = 18–30° K at pressures up to 110 atm. The adiabatic compressibility is obtained. The experimental results are analyzed in terms of a variant of perturbation theory which takes into account the quantum properties.
