摘要：

We have measured the shear modulus of bcc solid3He at 827 Hz using the high- Q torsional oscillator technique. We observed a decrease in the shear modulus from the low-temperature value G0to about 0.4G0at a molar volume of 24.80 cm3/mole and to 0.6G0at 24.32 cm3/mole near the melting point. The reduction of an effective shear modulus is explained by the dislocation theory of Granato and Lücke.
