Pressure Dependence of Superfluid Transition Temperature in 3He-4He Mixtures

Cooperative self-diffraction in an optical cavity

“…Experimental phase diagrams (London 1954, Satoh and Kakizaki 1972, Taconis and de Bruyn Ouboter 1964, Wallace et a1 1972 together with the theoretical results of Blume et a1 show that 3He-4He mixtures are almost ideal in the temperature region 2-5 K, so that we may choose Z = 0. The interactions J33 and JU are then determined from the critical temperatures T : and T:: J33 = 6.68 and JU = 10.50, whence: J34 = 8.59 and 1 = 1.91.…”
