WebIII lines have been considered to be He II fluorescence lines from the UV He II line, named O III Bowen lines after the researcher who first reported them (Bowen 1934, 1935). Later, many other channels were found. One of them is an O III fluorescence mechanism, resulting from the line matching of O III λ 374.436 (2p3s 3P 1-2p2 P 2

WebThis is Bowen fluorescence, and there are other examples elsewhere in astronomical spectroscopy. In the 1930s, Bowen played a major role in the optical design of the 200‐in. telescope on Palomar Mountain as well as other optical equipment. Bowen built a novel device, called an image slicer, which placed the spectra of successive strips across ...
WebOct 27, 2024 · Bowen fluorescence (Bowen 1928; Weymann and Williams 1969) is a process by which extreme-ultraviolet and X-ray photons ionize He II, which later recombines, emitting Ly-\(\alpha \) photons.
