✦ Synopsis

Transport coefficients are computed near the A-transition of helium by considering processes in which one transport mode breaks up into several. The conclusions are that first sound damping diverges as / E l-l, second sound damping as 1 E I-lls and thermal conductivity as 1 E /-II3 with E = (T -TA)/T, for low frequencies. These results were first obtained via the dynamical scaling idea by Ferrell and coworkers. Less singular results are found at higher frequencies.

For stabilizing the temperature of superfluid helium dc 1 or ac 2,3 bridge circuits are usually employed, in which the temperature probe is a resistance thermometer and the power dissipated in a wire heater is proportional to the out-of-balance signal.
