We remark that, during crystallization or melting, due to the structural difference between solid and liquid, the atoms have to rearrange themselves at the interface. This results in a supplementary surface « kinetic » energy. We examine the consequence of this term in the case of 4He where the interface is very mobile. The dispersion relation for crystallization waves becomes linear : ω = c0 k. The phonon transmission through the interface is enhanced. The Kapitza resistance is thus decreased, but presents always the anomalous dependence R K ∝ T-5 predicted by Marchenko and Parshin on other grounds.Nous remarquons que, lors de la fusion ou de la croissance d'un cristal, les atomes se réarrangent à l'interface à cause de la différence de st...
