Abstract : An interferometer was used to explore the equation of state of 4He below its critical point. A new absolute determination of the critical pressure by meniscus disappearance and reappearance gives the value P(c) = (1705. 84) Torr, corresponding to a critical temperature T(c) = (5.1897)K on the T(58) scale. New precise measurements of the density along the coexistence curve are shown. (Author)
