He covers the role of singular solutions of quantal equations in atomic physics, the classical description of crossings of energy terms and of charge exchange, classical stationary states, understanding the role of the singular spin-spin interaction in the binding energy of two-electron atoms/ions, the last observed line in the spectral series of hydrogen lines
in magnetized plasma: s revision of the Inglis-Tellor concept, and extrema in transition energies resulting not in satellites but in dips within spectral lines.
Tenders are invited for globe valves for hydrogen lines
AM CVn stars differ from most other cataclysmic variables (CVs) in the lack of hydrogen lines
from their spectra.
A minor objection to the use of Stark broadening to explain the width of the hydrogen lines
in the gaseous models rests on the fact that the appropriate experiments on hydrogen plasma do not exist.
On August 8, 1872, he photographed Vega through a 28-inch Cassegrain telescope of his own design and manufacture, showing four prominent hydrogen lines
A sampling of topics: the microstructure of a sunspot penumbra, penumbral moving magnetic features, SOLIS-VSM solar vector magnetograms, multigrid methods for polarized radiative transfer, tunable narrow-band filter for imaging polarimetry, the diffraction limited spectro-polarimeter, a brief overview of the Second Solar Spectrum, polarizability factors for molecular bands, spectro-polarimetry of cool stars, molecular diagnostics of the internal structure of starspots and sunspots, and the effect of turbulent electric fields on the scattering polarization of hydrogen lines
Any appliance must have its hydrogen lines
cleaned and purged before charging a metal hydride vessel; if not, contamination of the cartridge is almost a certainty.

The hydrogen lines
ofthe Balmer series, and, as Babcock has recently shown, ofthe Paschen series as well, are very strong in the Sun, though the energy required to put an atom into condition to absorb these series is, respectively, 10.
Its already inconspicuous hydrogen lines
became weaker, whereas lines from elements such as scandium, rubidium, yttrium, zirconium, barium, and tin started to appear.
On the first commissioning flight, EXES observed emissions from Jupiter's atmosphere in two molecular hydrogen lines
Beginning in 1890 Pickering and Fleming expanded Secchi's groups with Roman letters A through O, based primarily on the strengths of the observed hydrogen lines
(P and Q were used for those that did not fit).
