  • Diffusion in two-component quasiparticle systems of liquid and solid mixtures of helium isotopes 
    Adamenko, I.N.; Nemchenko, K.E.; Zhukov, A.V.; George, T.F.; Pandey, L.N.; Um, Chung-In (Condensed Matter Physics, 1999)
    An exact expression for the diffusion time which depends on the interaction rates for particles of not only different, but also of the same species, has been derived from the system of kinetic equations. The result is ...
  • Viscosity and ultrasonic attenuation in ⁴He below 0.6 K 
    Chung-ln Um; Soo-Young Lee; George, T.F.; Pandey, L.N.; Adamenko, I.N. (Физика низких температур, 1997)
    Through a treatment of three-phonon processes, the wide-angle scattering rates and the absorption rates of phonons, which characterize viscosity and ultrasonic attenuation, respectively, are calculated for ⁴He below 0.6 ...
