Cooperative laser–electron–nuclear processes: QED calculation of a spectrum of electron–nuclear γ‐transitions of a nucleus in the neutral atom

Abstract

ABSTRACT:A consistent quantum electrodynamics (QED) perturbation theory approach is applied to the calculation of the electron-nuclear ␥-transition spectra of the nucleus in the neutral atom. Satellite intensities are defined in the relativistic version of the energy approach (S-matrix formalism). The nuclear transitions in the isotopes of Ne 21 with energy 6 MeV and Ca 41 with energy 3 MeV are considered. The results of the calculations of the relative satellite intensities for different transitions in the neutral atoms Ne, Ca are presented.

Sensing the Recoil Induced Excitation and Ionization in Atoms and Ions Due to the Capture of Neutron and Alpha-Particle

“…In last years a development of methods of the laser spectroscopy allowed observing and further using the little changes in structure of atomic and molecular spectra because of the corresponding alteration of the internal state of a nucleus [1][2][3][4][5][6][7][8][9][10][11][12]. It should be mentioned a selective photoionization of atoms with the isomer nucleus and possibility of the quick physical separation of the isomer nuclei.…”

“…It is obvious that accounting for next perturbation theory order can increase the accuracy. Calculation of all matrix elements has been carried out according to papers [11][12][13][14][15].…”

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

“…[1][2][3][4][5][6][7][8]). It is stimulated by appearance of the intensive neutron pencils, powerful laser sources etc.…”

“…In particular, the exploration of nuclear emission or absorption spectrum for diatomic molecules is a subject of our interest. This spectrum contains a set of electronvibration-rotational satellites, which are arisen due to the alteration of the corresponding molecular states during the interaction of molecules with intense laser (gaser)fields [1,[4][5][6][7][8].The mechanism of forming the corresponding satellites in molecular spectra is connected with the shaking of electron shells resulting from the interaction between nuclei and γ quantums. The well known example is the Szilard-Chalmers effect (molecular dissociation because of the recoil during radiating gamma quantum with large energy) [1].…”

SENSING NEW g- QUANTUM-MUON-NUCLEAR INTERACTION EFFECTS: DISCHARGE OF METASTABLE NUCLEI DURING MUON CAPTURE

“…A comprehensive QED theory of cooperative laser-electronnuclear processes is developed in refs. [1,2,[10][11][12][13][14][15]. An effect of electron shell is quite small as the parameter r n /r a is small (r n is a radius of nucleus and r a is a radius of atom).…”
