Abstract: (Elsevier)

A sample of 115 K e4 + (e + ) decays has been obtained in a heavy liquid bubble chamber. The decay rate is given, together with the form-factors and mean ππ phase-shift as determined by a maximum likelihoog method.

k+: leptonic decay
leptonic decay: k+
final state
2pi+: electron: neutrino
pi pi: partial wave
form factor
bubble chamber(heavy liquid): experimental results
