Infrared Studies of Molecular Ions in Labortory and Space Plasmas and In Cryogenic Solid

9321913 Oka这项工作继续成功地观察和分析了行星电离层和超新星1987A中H3+的强红外辐射。这项工作将继续在其他天体中寻找H3+光谱，特别是在分子云中。实验和理论研究将尝试使用热的实验室等离子体和新的近红外激光器以及中红外激光源。两个新的放电电池将用于识别分子离子的新光谱。我们将下定决心，利用空心阴极放电电池在磁场中识别质子化甲烷和氧的光谱。此外，将介绍一种新的离子光谱方法，使用电离低温固体代替热等离子体。来自60Co的伽马射线将被用来电离对氢晶体，形成原子和离子团。傅里叶变换光谱仪和可能的激光光谱仪将被用来观察它们的红外光谱。如果成功，该方法将通过在晶体中引入其他分子作为杂质来扩展到其他簇离子。＊＊＊

9321913 Oka This work continues the success efforts to observe and analyze their strong infrared emissions of H3+ in planetary ionospheres and possibly in supernova 1987A. The effort will be continued to find the H3+ spectrum in other astronomical objects, especially in molecular clouds. The experimental and theoretical studies will be attempted using hot laboratory plasmas and new near infrared lasers along with midinfrared laser sources. Two new discharge cells will be used to identify novel spectra of molecular ions. A determined effort will be made to identify spectra of protonated methane and oxygen using a hollow cathode discharge cell in a magnetic field. Furthermore, a new method of ion spectroscopy will be introduced using ionized cryogenic solids instead of hot plasmas. Gamma rays from 60Co will be used to ionize para-hydrogen crystals to form atoms and ion clusters. A Fourier transform spectrometer and possibly laser spectrometer will be used to observe their infrared spectra. If successful, the method will be extended to other cluster ions by introducing other molecules in crystals as impurities. ***
