We have studied ultrasonic attenuation in rotating sHe-B at low pressures (< 10 bar) in magnetic fields up to 300 mT. In a strong field, the energy gap A in sHe-B is anisotropic, and the attenuation a of zero sound depends on the orientation of A. Because vortices and the counterflow between the nor
The frequency and temperature dependence of the electronic attenuation of longitudinal ultrasound in indium along [110] has been measured between 1.5 and 4.2 K in the frequency range 10-90 MHz. The zero-field results are well described by a modified free-electron Pippard expression. As expected from
