Notes: Abstract The spin content of the proton is investigated by studying the flavor singlet axial structure of the nucleon in a non-topological chiral soliton model. In order to construct a nucleon state we used the generator coordinate projection method as well as a coherent state for the meson wave function. Using a standard set of parameters we found the value g A 0 ≃ 0.44 for the flavor singlet axial vector coupling constant. This result is not far from that of a typical valence quark model.
