A model containing a nonet of scalar mesons S, a nonet of pseudoscalar mesons P, and a nonet of baryons is constructed where the mesons erter in the form of the matrix M = e/sup i(S+iP)/. Several Lagrangians are irtroduced such that the mesons get their physical masses, and the decay widths of the scalar mesons are calculated. The model satisfies generalized PCAC. It is found that the coupling constants of the mesons epsilon (700) and epsilon '(1060) to pions and nucleons satisfy the relations: G/sub epsilon NN//G/sub epsilon pi pi /= 1.4, G/ epsilon 'NN// G/sub epsilon ' pi pi = 0.89, G/sup pi pi //G/ sub NN//4 pi = 4.9, and G/sub epsilon ' pi i/G/sub epsilon 'NN//4 pi = 0.34.
