Measurements of Photoabsorption Cross Sections of Solar System and Cosmic Gases Under In-Situ Conditions

9317612 Wu：太阳系和宇宙气体在原位条件下的光吸收截面测量。吴博士和他的合作者已经成功地对太阳系和宇宙气体中存在的几种分子的高分辨率、低温和室温光吸收截面进行了实验室测量。他们将继续这项研究，将其应用于测量4PG体系的横截面、卡梅伦带、潜在的禁止过渡和CO的伪连续体，以及氨和几种重要碳氢化合物（包括烯、甲基乙炔、甲基乙烯、环丙烷、二乙炔和三乙炔）的横截面，从它们各自的吸收阈值到1060埃。在类似于现实行星大气的条件下，将研究诸如氢分子和氮分子等摄动物对所感兴趣的流产体的压力影响。

9317612 Wu Measurements of Photoabsorption Cross Sections of Solar System and Cosmic Gases Under In-Situ Conditions. Dr. Wu and his collaborators have successfully performed laboratory measurements of high resolution, low- and room-temperatuare photoabsorption cross sections of several molecules present in Solar System and cosmic gases. They will contine this research by applying it to the measurement of the cross sections of the 4PG system, Cameron bands, the underlying forbidden transitions and the pseudo-continuum of CO and to the cross sections of ammonia and several important hydrocarbons including Allene, Methyl Acetylene, Methyl Ethylene, Cyclopropane, Diacetylene, and Triacetylene, from their respective absorption thresholds to 1060 Angstroms. The pressure effects of perturbers such as molecular hydrogen and nitrogen on the aborbers of interest will be studied under conditions similar to those found in realistic planetary atmospheres.
