Abstract: (Elsevier)

From a study of 1609 K e4 decays we present: 1) a test of locality in weak interactions; 2) an evaluation of the energy dependence of the ππ phase shift δ s o , and of the scattering length a o .

k: leptonic decay
leptonic decay: k
weak interaction
pi pi: interaction
interaction: pi pi
partial wave
scattering: length
length: scattering
form factor
energy range 0.1 to 2 gev
