88Kr is one of the important gaseous fission products for determining the burn up of nuclear fuel with a short half-life, high fission yield and high branch ratio of γ-ray. Due to the more uncertainty of evaluated data and rare experimented data, 88Kr is one of the important gaseous fission products for determining the burn up of nuclear fuel with a short half-life, high fission yield and high branch ratio of γ-ray.
