In this paper we study the modification of the properties of the nucleon inthe nucleus within the quark-soliton model. This is a covariant, dynamicalmodel, which provides a non-linear representation of the spontaneously brokenSU(2)_L X SU(2)_R symmetry of QCD. The effects of the nuclear medium areaccounted for by using the Wigner-Seitz approximation and therefore reducingthe complex many-body problem to a simpler single-particle problem. We find aminimum in the binding energy at finite density, a change in the isoscalarnucleon radius and a reduction of the in-medium pion decay constant. The latteris consistent with a partial restoration of chiral symmetry at finite density,which is predicted by other models.Comment: 30 pages, 13 figures; uses REVTeX and epsfi
