摘要：
Using the phonon part of the effect Hamiltonian or Mishra and Tripathy (J Low Temp, Phys 75 (1989) 79), we have calculated the compressibility and thermal expansion parameter for liquid He-3 as a function of pressure with fixed temperature using the contact interaction potential and pseudopotential of Aldrich and Pines. With the help of two adjustable parameters one for local field correction effects and other. due to damping of zero sound mode, our calculated values are in good agreement with the experimental data.
