WebThe nuclear structure function F 3A at small x is investigated in two different theoretical models: a parton-recombination model with Q 2 rescaling and an aligned-jet model. We find these models predict completely different behavior at small x: antishadowing in the first parton model and shadowing in the aligned-jet model. WebShadowing is a quantum phenomenon leading to a non-additivity of electroweak cross sections on nucleons bound in a nucleus. It occurs due to destructive interference of amplitudes on different nucleons. Web1 aug. 2024 · The intense energy released during an atomic explosion is the result of nuclear fission.
