    "abstract": "The improved quark mass density- dependent model which includes the coupling\nbetween the quarks and a non-linear scalar field is presented. Numerical\nanalysis of solutions of the model is performed over a wide range of\nparameters. The wave functions of ground state and the lowest one-particle\nexcited states with even and odd parity are given. The root-mean squared\nradius, the magnetic moment and the ratio between the axial-vector and the\nvector beta-decay coupling constants of the nucleon are calculated. We found\nthat the present model is successful to describe the properties of nucleon.",
