Atomic electron distribution and recoil effects following beta decay of the halo nucleus helium-6

[摘要] Following the β decay of a6He nucleus to form6Li, the atomic electrons adjust to the sudden change of nuclear charge from 2 to 3. The probabilities for electron shake-up and shake-off are calculated, including recoil effects, by the use of a Stieltjes imaging representation of the final states. The results will be applied to ongoing angular correlation studies in a search for new physics beyond the Standard Model.
