摘要：
Measurements of the density equilibration in He-3 after a step change in temperature are reported along the critical isochore as a function of reduced temperature epislon above and below the critical point T(c), with 10(-6) < \epsilon\ < 10(-1). The equilibration process was followed s separately in the liquid and the vapor phases below T(c) where we observe different equilibration profiles. The relaxation time above T(c) is discussed in terms of the thermal diffusivity.
