Abstract: | This paper presents the results of a numerical solution of the Lamm equation for roton slowing specified by ω2 = ω02 exp {– λτ}, for parameters relevant to equilibrium experiments. It. is shown that in the two-component system it is theoretically possible to deduce s/D from measurements of the difference of concentration across the. cell with rotor slowing, provided that the time at which the difference reaches a maximum is known. |
