| Popis: | The dependence of the yield of near-zero-energy electrons (e0 electrons) from the surface of a 46Sc source on the energy of β− particles is measured with the use of the method of eγ and eβ coincidences. The self-ionization of an atom in β− decay owing to shake-off and direct collisions is determined. It is found that the probability of shake-off is independent of the energy of a β− particle, whereas the probability of direct collisions is inversely proportional to its velocity. The results of the measurements are discussed in the approximation of the sudden perturbation of an atomic electron by the moving β− particle. |
