Abstract
An experiment on the decay ${K}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{e}^{+}\ensuremath{\nu}$ was performed at the CERN proton synchrotron with spark-chamber and counter techniques. The ${K}_{e4}$ branching ratio has been measured relative to the $\ensuremath{\tau}$ decay. The $\ensuremath{\pi}\ensuremath{\pi}$ phase-shift difference ${\ensuremath{\delta}}_{0}^{0} \ensuremath{-} {\ensuremath{\delta}}_{1}^{1}$ and the form factors of the hadronic current have been determined as functions of the $\ensuremath{\pi}\ensuremath{\pi}$ energy. The $\ensuremath{\pi}\ensuremath{\pi}$ scattering length ${a}_{0}^{0}$ has been evaluated from the phase shifts with a phenomenological model. The results are compared with the theoretical predictions of current algebra and other models.
