Abstract

The low-energy spectrum of electrons emitted while bombarding a titanium target with b-particles obtained from a tritium source has been studied using the (be)-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 a-particles ejected in the decay of 238Pu. 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.
