K-shell double ionization probability was defined. Direct process domination in Ag atoms excitation was shown. Conversion coefficients were measured for M1 and E1-transitions in 44Ti decay with a high accuracy using sum peaks and multidimensional coincidence methods. It has been shown a significant contribution of penetrations effects for M1-transition and penetration parameter was obtained. The hypersatellites generation has been studied during the internal electron conversion process of the g-transitions in 109Ag,123Te and 147Pm nuclei. K-shell double ionization probability was defined in this nuclei and additional hypersatellite transition shifts were measured. The yields of e0-electrons emitted from the surface of thin films have been studied after bombardment with b-particles from the radioactive sources with 152Eu, 154Eu and 226Ra by the method of (еg)-coincidences. The yields of e0-electrons are found to be inversely proportional to the velocity of incident b-particles. This means that the ionization of target atoms is proportional to the duration of the perturbation induced by b-particles passing near the atom. Product Description popup.authors І.М.
