## Surface Waves on the Superfluids 3He and 4He

Free surface waves were examined both in superfluids (Formula presented.)He and (Formula presented.)He with the premise that these inviscid media would represent ideal realizations for this fluid dynamics problem. The work in (Formula presented.)He is one of the first of its kind, but in (Formula presented.)He, it was possible to produce a much more complete set of data for meaningful comparison with theoretical models. Most measurements were performed at the zero temperature limit, meaning (Formula presented.) 100 mK for (Formula presented.)He and (Formula presented.) 100 (Formula presented.)K for (Formula presented.)He. Dozens of surface wave resonances, including up to 11 overtones, were observed and monitored as the liquid depth in the cell was varied. Despite of the wealth of data, perfect agreement with the constructed theoretical models could not be achieved.
