The elastic constants of NaCl at 77.3°K and 4.2°K

The adiabatic elastic constants of NaCl have been measured at 77.3°K and 4.2°K using the ultrasonic pulse echo technique. The results are as follows (in units of 1011 dyne cm−2: C'11C'C'4477.3°K4.8072.2721.3354.2°K4.8502.3211.337 where C'11 = 12(C11+C12+2C44) and C' = 12(C11...

Description
Summary:The adiabatic elastic constants of NaCl have been measured at 77.3°K and 4.2°K using the ultrasonic pulse echo technique. The results are as follows (in units of 1011 dyne cm−2: C'11C'C'4477.3°K4.8072.2721.3354.2°K4.8502.3211.337 where C'11 = 12(C11+C12+2C44) and C' = 12(C11−C12). These values have been used to calculate the adiabatic bulk modulus and to re-evaluate the low temperature value of the Gruneisen parameter as determined from thermal expansion data and microscopic mode gammas.
