This research will measure (1) high-resolution, high- and room-temperature photoabsorption cross sections of molecular nitrogen and oxygen in the extreme ultraviolet region, and (2) temperature-dependent fluorescence cross sections for producing (a) neutral nitrogen emissions through photodissociative excitation of molecular nitrogen, and (b) ionized nitrogen 1085 and 916 angstrom emissions through dissociative photoionization excitation of molecular nitrogen. This work will utilize existing instrumentation, including windowless high temperature absorption cells and a high temperature effusive gas cell.

这项研究将测量(1)分子氮和氧在极端紫外区的高分辨率、高和室温的光吸收截面，以及(2)产生(A)通过分子氮的光解离激发产生的中性氮发射的随温度变化的荧光截面，(B)通过分子氮的解离光离激发产生的电离氮1085和916埃的发射。这项工作将利用现有的仪器，包括无窗高温吸收池和高温热气室。
