| Abstract: | The first measurements of acoustic reflection, together with acoustic transmission at the solid-liquid interface of4He, are used to determine the total relative acoustic energy absorption at the interface as a function of temperature. Based on these results, a new mechanism for the temperature dependence of the kinetics of growth and interface mobility is proposed. |
