COOPERATIVE LASER-ELECTRON-NUCLEAR OPTICS: NEW EFFECTS FOR ATOMS, IONS AND DIATOMICS. POLARIZATION OF NUCLEI UNDER RESONANCE IONIZATION — •Svetlana Malinovskaya — Computer centre Trust, P.O.Box 116,Odessa-9, 65009, Ukraine

This paper goes on our study of co-operative dynamical phenomena due the interaction between atoms, ions, molecules electron shells and nuclei nucleons. We consider a creation of additional satellites and narrow resonances inside the Doppler contour of Y line and governing by the intensity of complicated Y transitions due to the change of molecular excited states population under laser radiation action. Relativistic calculations of the complex laser- electron-nuclei systems are czarried out. Under emission (adsorption) of the nuclear Y quantum in atom or molecule a simultaneous change of the electron, vibration and rotation states has taken place. We use a consistent QED approach (Gell-Mann and Low formalism) to calculation of the electron-nuclear Y transition spectra (set of vibration satellites) of nucleus in the neutral atoms, ions and diatomic. QED is needed to describe correctly different channels of the electron nuclear processes. Decay probability are linked with imaginary part of the nucleons-electron shells-field system. Nuclear transitions in the isotopes of neon and iron are considered and results for electron-nuclear Y transition spectra are presented. The problem of the nuclei polarization (NP) under resonance ionization is also considered. Calculation of the NP degree in dependence upon the atoms light field parameters QED approach and polarizational density matrix formalism is carried out.
