	Study of the $K^{-}\!\!\rightarrow \pi^{0} e^{-} \nu $ Decay
	Protvino, 2001.- p.8, figs. 6, tables 2, refs.:15.

The decay $K^{-}\!\!\rightarrow \pi^{0} e^{-} \nu$ has been studied using inflight decays detected with ``ISTRA+" 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 formfactor has been measured: $\lambda_{+}= 0.0293 \pm 0.0015(stat) \pm 0.002(syst)$. The limits on the possible tensor and scalar couplings have been derived: $f_{T}/f_{+}(0)=-0.045 \pm 0.060(stat) ; $ $f_{S}/f_{+}(0)=-0.020 \pm 0.025(stat). $
