Abstract

The K⁺\ensuremath→\ensuremathπ⁰\ensuremathπ⁰e⁺\ensuremathν(K_e4⁰⁰) decay has been measured with stopped positive kaons for a data sample of 216 events. A comparison of the observed spectra with a Monte Carlo simulation determined the K_e4⁰⁰ form factor. The results are compatible with the K⁺\ensuremath→\ensuremathπ⁺\ensuremathπ^\ensuremath-e⁺\ensuremathν data, as estimated from the \ensuremathΔI=1/2 rule. We also established that the K_e4⁰⁰ channel can be used to determine the \ensuremathπ\ensuremath-\ensuremathπ scattering lengths.
