Spin polarized deuterium

Several ground state properties of (electron) spin-polarized deuterium (D) such as the energy, single quasiparticle energies and lifetimes, Landau parameters and sound velocities are evaluated. The calculations begin with the Kolos-Wolneiwicz potential and use the Galitskii-FeynmanHartree-Fock (GFHF) approximation. The deuteron nucleas has spin I = 1, and spin states I/sub z/ = 1,0,-1. We explore D1, D2 and D3 in which, respectively, one spin state only is populated, two states are equally populated, and three states are equally populated. We find the GFHF describes D1 well, but D2 and D3 less well. The Landau parameters, F/sub L/, are small compared to liquid 3He and very small for doubly polarized D1 (i.e. the F/sub L/ decrease with nuclear polarization)
