Using Wigner distributions, the authors find that the fraction of baryons with quark phase-space occupancy above the Pauli bound tends to a constant for heavy nuclei, supporting the plausibility of low-momentum suppression.

abstract
We describe the first version (v1.00) of the code HFBRAD which solves the Skyrme-Hartree-Fock or Skyrme-Hartree-Fock-Bogolyubov equations in the coordinate representation within the spherical symmetry. A realistic representation of the quasiparticle wave functions on the space lattice allows for performing calculations up to the particle drip lines. Zero-range density-dependent interactions are used in the pairing channel. The pairing energy is calculated by either using a cut-off energy in the quasiparticle spectrum or the regularization scheme proposed by A. Bulgac and Y. Yu.

Quark Phase Space Distributions in Nuclei
Using Wigner distributions, the authors find that the fraction of baryons with quark phase-space occupancy above the Pauli bound tends to a constant for heavy nuclei, supporting the plausibility of low-momentum suppression.
