  • Finite temperature effects in the Fermi liquid theory of the diffusion of ⁴He in ³He 
    Hjort, H.H.; Culman, T.G.; Edwards, D.O.; Jizhong He (Физика низких температур, 1997)
    The diffusion coefficient D and the thermal diffusion ratio kT for dilute ⁴He in liquid ³He are calculated from Fermi liquid theory. The collision integral assumes a scattering amplitude a³⁴ expanded in scalar combinations ...
  • Finite-Temperature Form Factors: a Review
