Abstract
Our recent high-resolution interferometric investigations on He-4 soli d/superfluid interfaces have revealed interesting static and dynamic p henomena in quantum crystals. In this work we have initiated studies o f He-3 crystals and developed a new optical setup which combines two i nterferometric principles with different resolutions. Our setup allows determination of overall crystal shapes as well as high-resolution st udies of facets down to millikelvin temperatures.
