9322384 Wu This award is for measuring (1) high-resolution high-, room-, and low-temperature photoabsorption cross sections of molecular nitrogen and (2) the temperature-dependent fluorescence cross sections for producing the N I emissions through photodissociative excitation of molecular nitrogen and that for producing the N II 1085 and 916 angstrom emissions through dissociative photoionization excitation of molecular nitrogen, from their respective thresholds to 200 angstroms. Such cross sections are required for accurate quantitative analysis and evaluation of the nitrogen dayglow models of the Earth, Titan and Triton. ***

该奖项用于测量(1)分子氮的高分辨率、室温和低温光吸收截面，以及(2)通过分子氮的光解离激发产生氮氧化物发射的温度依赖荧光截面，以及通过分子氮的离解光电离激发产生氮氧化物1085和916埃发射的温度依赖荧光截面。从各自的阈值到200埃。这样的横截面是精确定量分析和评估地球、土卫六和海卫一的氮日光模型所必需的。＊＊＊
