The He ( I ) and He ( II ) Photoelectron Spectra of
U V photoelectron spectra of the title com pounds are rep orted . A ssignm ents are m ade with the help of H e(I)/H e(II) intensity differences, shift effects upon substitu tion and com parison with re la ted m olecules. Previously draw n conclusions about the electronic structure of similar com plexes also hold for the com pounds. It is indicated that the ionization energy for the sym m etri...

متن کاملTheoretical calculations of the H I , He I and He II free - bound continuous emission spectra
We present coefficients for the calculation of the continuous emission spectra of H I, He I and He II due to electron-ion recombination. Coefficients are given for photon energies from the first ionization threshold for each ion to the n = 20 threshold of hydrogen (36.5μ), and for temperatures 100 K ≤ T ≤ 10 K. The emission coefficients for He I are derived from accurate ab initio photoionizati...
متن کامل2D non-LTE radiative modelling of He I spectral lines formed in solar prominences
Context. The diagnosis of new high-resolution spectropolarimetric observations of solar prominences made in the visible and nearinfrared mainly, requires a radiative modelling taking into account for both multi-dimensional geometry and complex atomic models. Aims. Hereafter we contribute to the improvement of the diagnosis based on the observation of He i multiplets, by considering 2D non-LTE u...
متن کاملRadiative Transfer Effects in He I Emission Lines
We consider the effect of optical depth of the 2 S level on the nebular recombination spectrum of He I for a spherically symmetric nebula with no systematic velocity gradients. These calculations, using many improvements in atomic data, can be used in place of the earlier calculations of Robbins. We give representative Case B line fluxes for UV, optical, and IR emission lines over a range of ph...
