Absorption spectroscopy of radiatively-heated low-Z foils

High-resolution absorption spectra of radiatively-heated low-Z foils (CH and BN) have been recorded at the Nova II laser facility by a grazing-incidence spectrograph. Using a calibration curve for Kodak 101 photographic plates, the plate density was converted to relative intensity transmitted by the foil. Absorption spectra are presented for the elements B, C, and N. The absorption features near the nickel L edge in the wavelength region 11–15 Å are also presented.
