[2] In this study, rather than thermal desorption (with methanol released at temperatures higher than its sublimation temperature), other mechanisms are supported and discussed by the team, including photodesorption by ultraviolet photons and reactive desorption. (alma-telescope.jp)
Analysis of multiple diffraction images provides high contrast, high quality, full field 3D imaging of surfaces illuminated by extreme ultraviolet photons from a tabletop laser. (foresight.org)
In an optical telescope, photons strike a mirror or lens whose surface is nearly perpendicular to the light's path; but extreme ultraviolet photons hitting such a surface would get absorbed rather than reflected. (newscientist.com)
