Electron Collisional Broadening of Isolated Lines from Multiply-ionized Atoms
Recent experimental and theoretical (both improved semiclassical and fully quantum-mechanical) line broadening calculations for B III and NeVII ∆n = 0 transitions with n = 2 and 3, respectively, are discussed. The disagreements by about a factor of 2 between the fully quantum-mechanically calculated and both measured and semiclassically calculated widths can be explained in terms of violations ...
متن کاملEffect of multiple scattering on broadening and the frequency shift of spectral lines
The effect of multiple scattering on the broadening and the shift of the spectral lines of light propagating in a medium is investigated within Wolf’s framework. The condition for no blueshift is derived. It is shown that under the same hypothesis the property DvN11@dN is satisfied. Moreover, the no blueshift condition has been found to be closely related to the no blurring condition. These res...
متن کاملBroadening of Spectral Lines Due to Dynamic Multiple Scattering and the Tully-fisher Relation
The frequency shift of spectral lines is most often explained by the Doppler Effect in terms of relative motion, whereas theDoppler broadening of a particular line mainly depends on the absolute temperature. The Wolf effect on the other hand deals with the correlation induced spectral change and explains both the broadening and shift of the spectral lines. In this framework a relation between t...
متن کاملCore-polarization Effects for the Stark Broadening of Pb III Spectral Lines: Predictions and Regularities
Using a semi-classical approach, we have calculated values of the Stark broadening parameters for several lines of Pb III. Stark widths and shifts are presented for an electron density of 1017 cm– 3 and temperatures T = 11000-100000 K. In this work, we have carried out a study of the influence of the introduction of the terms that allow us to take into account the Core Polarization (CP) effects...
متن کاملMecanismos de alargamento de linhas espectrais atômicas Line broadening mechanisms of atomic spectral lines
Os espectros de energia de átomos idealizados (isolados, parados e em temperatura 0K) são constitúıdos por um conjunto de linhas muito estreitas. Contudo, no mundo real, verifica-se que cada uma destas linhas são alargadas pela ação de vários tipos de influências externas. Uma discussão simplificada é apresentada sobre seus mecanismos e como cada um deles atua isoladamente sobre as linhas espec...
