... these conditions, the VUV intensity is just equal to the known UV intensity multiplied by an attenuation factor and the PMT signals ratio. Using 16 mJ visible and 4 mJ UV input laser powers, we have measured ∼ 1013 photons/pulse (∼ 20 µJ/pulse) for the stronger one of two VUV emissions: the intensit ...

... is a (real) wavenumber of amplitude-bounded Bloch waves [14]. The bands are separated by spectral gaps in which Im(k) = 0. The solutions at the band edges are stationary Bloch states corresponding to the condensate density which is strongly and periodically modulated by the lattice. For an interact ...

Vacuum-UV spectroscopy of interstellar ice analogs. I. Absorption
... photons have the power to excite or dissociate molecules, leading to a complex chemistry in the grains. The VUV-region encloses wavelengths from 200 nm to about 100 nm, since the term extreme-ultraviolet (EUV) is often used for shorter wavelengths. The estimation of the VUV-absorption cross sections ...
