摘要：

The decay K- --> e(-)nupi(0) has been studied using in-flight decays detected with the ISTPA+ setup working at the 25-GeV negative secondary beam of the U-70 PS. About 130K events were used for the analysis. The lambda(+) parameter of the vector form factor has been measured: lambda(+) = 0.0293+/-0.0015(stat.) +/- 0.002(syst.). The limits on the possible tensor and scalar couplings have been derived: f(T)/f(+)(0) = -0.045 +/- 0.060(stat.) and f(S)/f(+) (0) = -0.019(-0.016)(+0.025) (stat.).
