Radiative Corrections to Decay Processes
Physical Review, 1956Radiative corrections associated with the electromagnetic field have been determined for the decay of a fermion of arbitrary mass into a lighter one with the emission of a single boson or of two other fermions; no special assumptions have been made about the nature of the interaction responsible for the instability.

Elementary Radiative Processes
2019Parameters of elementary processes involving photons and atomic particles are evaluated. These processes include photoionization of atoms, and photorecombination of electrons and atomic ions, photodetachment of negative ions, and photorecombination of electrons and atoms, photodissociation of molecules. Photoprocesses involving highly excited atoms are

Peter R Fontana 1982 New York: Academic xv + 270 pp price $32.50 ISBN 012 262 0208 The interaction of atoms with the electromagnetic fields in which they are immersed has long been a central topic of modern physics. Thus the classical work of Lorentz led naturally to the early quantum studies of Einstein, Dirac and Heitler, and this in its turn to the ...

Radiative Processes in Heterostructures
1999In this chapter we discuss the processes of spontaneous photon emission by quasi-equilibrium electron-hole pairs in heterostructures. Such processes are responsible for a variety of physical effects, from luminescence to las-ing. Many important device applications of heterostructures, such as lasers and light-emitting diodes, operate by using radiative

Elementary radiative processes
2007Abstract In this introductory chapter, we consider the elementary radiative processes for both free atomic particles (atoms, ions, and molecules) and particles interacting with a monochromatic laser field. For more advanced considerations, the reader is advised to refer to the classical textbooks (Loudon 1973; Sargent et al.

Tunnelling contribution in non-radiative processes
Solid State Communications, 1983Abstract A semiclassical formalism, already introduced to treat non-radiative processes in multidimensional spaces, has been extended to compute total non-radiative transition rates. A simple approximate analysis results in simple formulae which discriminate between quantum-tunnelling contributions and classical ones.

Radiative Processes, Spin Currents, Vortices
2021This chapter deals with developments that have their origin in subjects introduced in Chaps. 1 and 2. Gravitational Berry phases enable the formulation of an EFA which alters the dispersion relations of the particles interacting with the gravitational field.

Relativistic effect of atomic radiative processes
Physical Review A, 1994We present a theoretical study of the relativistic effect of atomic radiative processes. In order to avoid any entanglement of the atomic screening effect, we would like to elucidate the relativistic effect of the atomic radiative processes by examining the radiative processes of the hydrogenlike atomic ion system.

Radiative and non-radiative processes in jet-cooled NCNO
Chemical Physics Letters, 1987Abstract Lifetimes of excited vibronic levels in NCNO are measured both by LIF and by monitoring excited state absorptions. Fluorescence lifetimes are longer than S 1 radiative lifetimes at all wavelengths between the band origin (11339 cm −1 ) and D o (17085 cm −1 ).

Radiative Processes in Astrophysics
Physics Bulletin, 1980George B Rybicki and Alan P Lightman 1980 Chichester: John Wiley xv + 382 pp price £19 The interaction of radiation with matter is a subject of fundamental importance in astrophysics. It is far from being an easy one to teach, not the least of the problems being the lack of suitable texts in this area.
