Abstract

We present the results of an analysis of 8141

K_{e 4}

decays. These include (i) the form factors of the weak hadronic current and their dependences on the invariant di-lepton and di-pion masses, and (ii) the magnitude and dependence on invariant di-pion mass of the

π - π

scattering phase shift

δ_{s} - δ_{p}
