• The excitation spectrum of a nucleon with spin 1/2 is examined using the Friedberg-Lee model containing constituent quarks and a scalar meson. An appropriate method of quantization for the non-linear meson field is employed by taking account of the non-topological soliton existing at the classical level. Our model space for the nucleon resonances includes the three quark plus one meson state, in addition to the pure three quark state. The excitation spectrum in this model space reveals that the positive parity state appears as the first excited state associated with the Os-excitation of the scalar meson. The meson excitation also generates an additional negative parity state apart from the well-known Op-excitation of the quark.
