摘要
A statistical distribution model is developed for a mixture of bosons and fermions with different concentrations. The bosons and fermions are assumed to be interacting via a pair interaction. The most probable distribution in energy and the partition function are derived. Thermodynamic quantities such as entropy, internal energy and specific heat are obtained in terms of the partition function. The values of the internal energy, specific heat and entropy increase as the concentration of helium-3 in the mixture decreases.
