Abstract
Measurements of Young's Modulus and sound velocity of a range of sintered copper powder samples have demonstrated the existence of low frequency soft phonon modes that could explain the low temperature anomaly in the Kapitza resistance between liquid 3He and sintered metal heat exchangers below 10 mK.
