“…As the potential grows, the intensity of e 0 -peak rapidly falls down, and it almost completely disappears at the energy eU = 24 eV. We have studied the properties of e 0 -electrons thoroughly enough in works [9][10][11][12]; therefore, we dwell now on them only shortly. For the illustrative purpose, in Fig.…”

The low-energy spectrum of electrons emitted while bombarding a titanium target with β-particles obtained from a tritium source has been studied using the (βe)-coincidence method. To reveal common features and distinctions of this process for different charged particles under the same experimental conditions, including the same target, similar measurements are carried out using α-particles ejected in the decay of 238 Pu. It is shown that the ionization of atoms in the target at its bombardment with charged particles can be represented in the both cases as a result of the shake-off process.

“…The latter has been studied the most comprehensively in the case of β-decay, when an electron is shaken off from the atomic shell, and, as a result, the charge of the nucleus changes by +1 in a jump-like manner. In a series of works [5][6][7][8][9], we analyzed the yield Y of e 0 -electrons into vacuum and its dependence on the kind of radioactive decay, radioactive source thickness, magnitude of charge that arises in the course of the radioactive decay, and velocity of charged particles that cross the target surface. In this work, our efforts will be focused on the determination of the e 0 -electron distribution over energies and the binding energy of e 0electrons, E n , before they are emitted from the source or target surface.…”

Energy Distribution of Electrons in the “Zero-Energy Peak” Induced by a Radioactive Decay or a Target Bom-bardment with Charged Particles

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.
