The Theory and Experimental Investigation of Controlled Spontaneous Conversion Nuclear Decay of Radioactive Isotopes

The presented paper discusses the theory and results of direct experimental investigation of the control of internal electron conversion channel of radioactive isotopes spontaneous decay by controlling action of oriented crystal matrix on motion of conversion electrons. The same effect takes place at any β-processes (including at decay of a neutron with an emission of electrons and neutrino). It was shown that parameters of internal electron conversion decay greatly depend on structure of crystal matrix and on distance from excited nucleus to crystal matrix.
