On the basis of the structural model of stratons, we discuss semi-leptonic decays of (1/2)+ baryons and elastic and quasi-elastic neutrino reactions, using the effective Ha-miltonian of weak interaction for stratons and leptons in [1] and the (1/2)+ baryon wave functions in [2] and the parameters determined by electromagnetic processes in [3]. The theoretical results of the semi-leptonic decays are in good agreement with the experimental results. The axial-vector form factor of △S = 0 processes and the total cross-sections of νμ+n→p+μ- agree with experiments within reasonable error. The axial-vector form factor of △S = 1 processes and the total cross-sections of νμ+p→Λ+μ+ also agree with the rough experimental data available.In particular, it is of interest to point out that, in our discussion, all the parame-ters involved were determined in [3], no new parameter has been introduced.
