In a very low momentum KL0 beam, a sample of KL0→π±eν decays has been identified in the 25-in. hydrogen bubble chamber by means of bubble density. Based on 531 events, the energy-dependence parameter for the Ke30 vector form factor was determined by λ=+0.01±0.015, which is consistent with no energy dependence.
