Specific heat of [formula omitted] film adsorbed on three-dimensional pores

We have measured heat capacities of 4 He and 3 He films adsorbed on a new mesoporous material with the pore diameter 27 A ̊ called HMM-2, which has an ordered 3D network of pores. The substrate is an organic–inorganic hybrid material made of C 2H 4 and Si 2O 3, and consists of cages connected in the...

Description
Summary:We have measured heat capacities of 4 He and 3 He films adsorbed on a new mesoporous material with the pore diameter 27 A ̊ called HMM-2, which has an ordered 3D network of pores. The substrate is an organic–inorganic hybrid material made of C 2H 4 and Si 2O 3, and consists of cages connected in the HCP structure (a=55.4 A ̊ , c=88.6 A ̊ ) . When adsorptions are above one layer, heat capacities are qualitatively different between 3 He and 4 He . It indicates that the Bose fluid of the 4 He film appears at the second layer.
