Spectroscopy of cooperative laser–electron nuclear effects in multiatomic molecules

A consistent quantum approach to calculating the electron–nuclear γ transition spectra (a set of vibration–rotational satellites in a molecule) of a nucleus in the multiatomic molecules is proposed and generalizes the well-known Letokhov–Minogin model. Estimates of the vibration–nuclear transition probabilities in a case of the emission and absorption spectrum of nucleus 188Os in the molecule of OsO4 and nucleus 191Ir in the molecule IrO4 are presented.

Consistent quantum approach to new laser-electron-nuclear effects in diatomic molecules

We present a consistent, quantum approach to the calculation of electron-nuclear γ. spectra (set of vibrational and rotational satellites) for nuclei in diatomic molecules. The approach generelizes the well known Letokhov-Minogin model and is based on the Dunham model potential approximation for potential curves of diatomic molecules. The method is applied to the calculation of probabilities of the vibration-rotation-nuclear transitions in a case of emission and absorption spectrum for the nucleus 127I (Eγ(0) = 203 keV) linked with the molecule H127I.

QUANTUM CALCULATION OF COOPERATIVE MUON-NUCLEAR PROCESSES: DISCHARGE OF METASTABLE NUCLEI DURING NEGATIVE MUON CAPTURE

There is presented a consistent energy approach to the quantum elec- trodynamics (QED) theory of the discharge of a nucleus with emission of a J radiation and further muon conversion, which initiates this discharge. A numer- ical calculation is carried out for nucleus 49 21 Sc28.

Consistent quantum theory of recoil induced excitation and ionization in atoms during capture of neutron

We present a consistent new theoretical scheme for the calculation of recoil-induced excitation and ionization in atoms and ions during the emission or capture of a neutral particle (neutron) or alpha particle. The perturbation theory on inter electron interaction as a method of the calculation of correlated electron wave functions is used. The numerical results for transition probabilities to different electronic states, induced by capture of a neutron by 3He, 19Ne8+ are presented.

Monte-Carlo Quantum Chemistry of Biogene Amines. Laser and Neutron Capture Effects

Monte‐Carlo quantum calculation of the cluster consisting of the serotonine ST (histamine HM) molecules and 100 molecules of water is carried out. It is found that the zwitterion appears as expected to be strongly favoured with respect to neutral molecule. The perspective possibilities of laser and neutron capture action on different biomolecules are indicated.

New Laser-Electron Nuclear Effects in the Nuclear γ Transition Spectra in Atomic and Molecular Systems

A consistent QED perturbation theory approach is applied to calculation of the electron-nuclear γ-transition spectra of nucleus in the multicharged ion. The intensities of satellites are defined in the relativistic version of the energy approach (S-matrix formalism). As example, the nuclear transition in the isotope 26 57 Fe with energy 14.41 keV is considered. The results of the relativistic calculation for the electron-nuclear γ-transition spectra (set of electron satellites) of the nucleus in a multicharged atomic ion FeXIX are presented. The possible experiments for observation of the new effect in the thermalized plasma of O- like ions are discussed. Consistent, quantum approach to calculation of the electron-nuclear γ transition spectra (set of vibration-rotational satellites in molecule) of nucleus in molecule, which generalizes the well known Letokhov-Minogin model, is presented and based on the Dunham model potential approximation for potential curves of the diatomic molecules. Estimates are made for vibration-rotation-nuclear transition probabilities in a case of the emission and absorption spectrum of nucleus 127I (E γ (0) = 203 keV) in the molecule of H127I. Estimates of the vibration-nuclear transition probabilities in a case of the emission and absorption spectrum of nucleus 191Ir (E γ (0) = 82 keV) in the molecule of IrO4 and nucleus 188Os (E γ (0) = 155 keV) in the molecule of OsO4 are presented too.

Advanced Quantum Mechanical Calculation of the Beta Decay Probabilities

Advanced theoretical schemes for calculating atomic chemical environment effect on the β decay characteristics are developed. As method of calculation of the relativistic atomic fields and electron wave functions, the gauge invariant Dirac‐Fock type and Dirac‐Kohn‐Sham approaches are used. The numerical results for atomic chemical environment effect on the β decay of the sulfur and plutonium are presented.
