Phys. Rev. C 65, 061303(R) (2002) [4 pages]Interaction induced deformation of the momentum distribution of spin polarized nuclear matter
Effects of spin polarization on the structure of symmetric nuclear matter and pure neutron matter are investigated. We show that spin polarization induces a deformation of the Fermi spheres for nucleons with spins parallel and opposite to the polarization axes. This feature can be related to the structure of the one-pion exchange contribution to a realistic nucleon-nucleon interaction. While the anisotropies in the momentum distribution lower the energy of the system by a small amount, the associated variations of the single-particle energies with the angle between the polarization axis and the particle momentum are significant. © 2002 The American Physical Society URL:
