Abstract

The temperature dependence of the mobility of the electron bubble in superfluid helium has been calculated1 using a hydrodynamic approach for the phonon-bubble scattering cross section. This calculation explains the observed T −3 dependence of previous experimental data2 in the range 0.33–0.5°K as arising from a prominent s-wave resonance in the bubble cross section for thermal phonons. Furthermore, this calculation predicts that the mobility at lower temperatures should rise more sharply than T −3. At very low temperature (T < 80 m°K) the mobility should vary as T −8. This behavior is characteristic of Rayleigh scattering. We have extended the measured temperature range down to 0.15°K and have observed that the mobility indeed increases faster than T −3.
