Specifically, an optical system and method are provided in which radiation reflected from a sample is used to determine surface topography characteristics of the sample, and in which an illumination source directs Lyman-伪 radiation at the sample in an environment that is at least partly an ...

TARAFDAR and Wickramasinghe1suggested that the Lyman alpha (Lα) intensity in the interstellar medium may be in the range (1–4) × 10−4erg cm−2s−1sr−1and have pointed out that, if this is the case, Lα may play an important part in photoemission from interstellar grains. He...

Lyman —α emission dominates the UV spectra of the roughly 18 radio galaxies observed to date with z > 1.6. I discuss three categories of such objects; (a) “normal”, large and distant radio galaxies with developed continuum structures, often...
Abstract Despite the energetic significance of Lyman-alpha (Lyα; 1216 Å) emission from solar flares, regular observations of flare related Lyαhave been relatively scarce until recently. Advances in instrumental capabilities and a shift in focus over previous solar cycles mean it is now routinely...
