As announced in last paper by the present authors, the color-singlet
three-quark states are investigated for the case of the spherical j-j coupling
and L-S coupling shell models. The latter case automatically leads to the
su(4)*su(4)-model. For a certain type of Hamiltonian, the states of individual
"nucleons" are characterized.Comment: 11 pages, 1 figure, using PTP clas
