摘要：

We have measured the shear modulus of bce solid He-3 at 827 Hz using the high-Q torsional oscillator technique. We observed a decrease in the shear modulus from the low-temperature value G(0) to about 0.4G(0) at a molar volume of 24.80 cm(3)/mole and to 0.6G(0) at 24.32 cm(3)/mole near the melting point. The reduction of an effective shear modulus is explained by the dislocation theory of Granato and Lucke.
