Abstract : A groundstate wave function for solid He3 in the body centered cubic phase is calculated in the form of a product of singleparticle orbitals and pair correlations. The correlation part is an eigenfunction of the Pluvinage Hamiltonian with each pair in a state of zero energy in a frame in which their center of mass is at rest. Assuming that exchange effects are small, we obtain an approximate singleparticle probability function from this wave function. The manybody energy is obtained from this singleparticle probability function from basic principles by a plausibility argument, and leads to a pressurevolume relation that is in good agreement with observation. Exchange effects arise from the original wave function, when suitably antisymmetrized. This predicts an exchange energy of about 0.005 K near the melting curve, in agreement with a recent experiment of Adams, Meyer, and Fairbank; this exchange energy favors antiferromagnetic alignment.
