Energy Distribution of Electrons in the “Zero-Energy Peak” Induced by a Radioactive Decay or a Target Bom-bardment with Charged Particles
Section: Nuclei and nuclear reactions
Original Author's Text: Ukrainian
Abstract: The energy distribution of near-zero electrons (e0-electrons) emitting from the surface of radioactive sources or from the surface bombardment with α- or β-particles is studied. The integrated spectrum N(E) of e0-electrons with the energy E = (0 ÷ 24) eV is determined from the measurements of the delay curve by applying a retarding potential between the source (or the target) and the detector of e0-electrons. The calculated distribution of e0-electrons is shown to be in good agreement with the theoretical one obtained in the framework of the shakeoff model, i.e. when the perturbation by an electric charge arising near the surface and it shakes off weakly bound electrons from the surface.
Key words: reflection, passing through, near zero electrons (e0-electrons), shakeoff effect, microchannel plates (MCP).
