Physics 541: Radiative Processes

 

Course Outline


Basic Material: Radiative transfer terms definition and usage, fundamental equation of radiative transfer and source function, electromagnetic spectrum regions and relationship to blackbody radiation, Einstein A and B coefficients

Fields: Maxwell equations and electromagnetic waves, power emitted from accelerated charges (amount, angular pattern, and polarization), four vectors and covariance, relativistic transformations involving E and B fields

Spectra and Scattering from Moving Charges: Physical basis of free-free and synchrotron radiation, spectrum of free-free, cyclotron, and synchrotron radiation, Compton scattering cross section and effect on spectrum, inverse compton scattering

Plasma Effects: Plasma effects of rotation measure and dispersion measure

Atomic and Molecular Structure and Spectra:

Basic atomic structure ofsingle-electron and multi-electron atoms, spectroscopic notation,definitions of permitted and forbidden emission lines, free-boundradiation spectrum, thermal, natural, and collisional line broadening,energy levels of diatomic, molecules and symmetries, rotation-vibrationspectra of molecules
