Abstract
Heat capacity measurements are described for films of pure4 He and a 12%He 3 mixture ofHe 3 andHe 4He adsorbed on copper, for 0.1<T<1.2 K.He 4 heat capacity isotherms show a step-type behavior as a function of coverage for the first two layers, while the mixture isotherms only show the first step. A comparison is made with recent multilayer data for helium films on Vycor published by other authors.
