Abstract
The decays K- --> mu(3)(-)V pi(o)(K-mu 3) and K- --> e-v pi(o)(K-e3) o bserved with the ISTRA-M detector operating at the 70-GeV Protvino acc elerator are analyzed. Under the assumption of mu-e universality, a si multaneous fit to K-mu 3 and K-e3 data yields the values of lambda(+)= 0.017 +/- 0.006 and lambda(o) = 0.057 +/- 0.017 for the form-factor p arameters.
