This enables to receive precision data on energy levels and their gamma-rays with precision of a few electron volts. Determined with high precision the energy of excited states 175Lu, 122Te, 122Sn and the energy of gamma-rays. Recommended use of them as energy normals of fourth order. Investigated anomalies in the internal conversion coefficients inhibited series rotary M1 transitions in 163Er, 165Ho, 175Lu, 177Hf, 191Ir. The experimental values of matrix element penetrations and calculated values of gs-factors for operators of spin-multipole interaction. In magnetic beta-spectrometer accurately measured intensity ratio of internal electron conversion on K- and L-shells, which indicates its collective nature. Theoretical description of electron emission of low energy (e0 - electrons) from the solids was created. Our studies confirm the theoretical description. According to our understanding the cause emission of e0- electrons is shake off the electrons from the surface, caused by the sudden appearance of a charge in the surface layer. The effect is similar to shaking off at beta-decay. The charge in the surface layer may occur in the process of radioactive decay and the bombardment of the target by charged particles. The theoretical description of the radiation e0- electrons based on the Schrodinger equation in the first approximation of perturbation theory and determined by formulas of works Landau and Livshits, taking into account the rapid emergence disturbance compared to the speed of light as well as the statistical distribution of the density levels of electrons in the final state of continuous spectrum. The process radiation takes place in two stages. The first stage of the process determines frequency of sudden perturbations e0 - electrons. It depends on the duration of the interaction, the charge density and e0- electrons on the surface of the target. The second stage of the process refers to the probability of transition from the initial state to the final state of the light distribution e0- electron energy in a continuous spectrum. It does not depend on the variety of incident particles, although it can not be happened without the first stage. In our work the process shaking off e0- electrons are considered only due to a sudden change of charge near the surface during radioactive decay or by bombarding a target charged particles. However, emission of e0- electrons can occur in cases where the sudden change of the charge comes as a result of spontaneous or forced other processes occurring near the surface. Different types of such secondary electron emission can distinguish one from the other in their first stage of the disturbance, but they must have the same second stage, which is well described by the formula where emission of e0 - electrons from a surface in a vacuum and their allocation to energy is considered to be the result of the shake off effect.
