项目摘要

電子-分子衝突を利用した分子の励起解離過程についての従来よりの研究を一段と発展させると共に, イオンー分子衝突室の試作を開始した.1.電子-分子衝突による分子の励起解離過程の解析(1)アセチレンの励起解離による励起水素原子生成過程を, バルマー線のドプラー線形及びその角度依存性を正確に測定し解析することにより研究した. 主要な励起水素原子生成過程が三つあり, それらのしきい値は20.8, 約30, 35-40eVで,それらの並進運動エネルギーは0-2, 3-5, 6-8eVであった. これらの非対称パラメーターはすべて正で, 直線構造から解離するとすれば平行遷移に基き, 中間状態の対称性はΣuである. 特に第一成分の非対称パラメーターは0.5であり, 中間状態は分子回転程度の寿命を有する.(2)水および水素分子より励起水素原子を生成する過程について, 解離成分別にファノプロットを測定し, 解離過程の対称性を定めた. 水については第一第三成分が光学許容, 第二第四成分が光学禁制と結論した. 水素では速い成分が光学禁制, 遅い成分が光学許容であった.(3)フルオロベンゼンの電子衝塑による親分子の発光スペクトルの振動構造を詳細に解析した. トルエンの場合と同様に光学許容な振動構造が支配的で禁制な準位が強かったベンゼンとは異なる. 励起関数をも測定した.(4)アセチレンの電子衝塑による親分子の発光スペクトルを測定した. 発光は240-400nm領域に現われ, 幅広く, Si-So遷移に帰属した.2.イオンー分子衝突による分子の励起解離過程の解析補助金により, イオン分子衝突室, 6インチトラップ, ゲーバルブ, 油回転ポンプを購入し, 油拡散ポンプは既設のものを転用し, イオンー分子衝突実験装置の組立てを行った. 目下イオン銃部分を調節中である.

1. Analysis of the excitation dissociation process of molecules in electron-molecular conflicts (1) The excitation dissociation process of molecules in electron-molecular conflicts (1) The excitation dissociation process of molecules in electron-molecular conflicts (2) The excitation dissociation process of molecules in electron-molecular conflicts (3) The excitation dissociation process of molecules in electron-molecular conflicts (4) The excitation dissociation process of molecules in electron-molecular conflicts (5) The excitation dissociation process of molecules in electron-molecular conflicts (6) The excitation dissociation process of molecules in electron-molecular conflicts (7) The excitation dissociation process of water atoms in electron-molecular conflicts (8) The excitation dissociation process of molecules in electron-molecular conflicts (7) The excitation dissociation process of water atoms in electron-molecular conflicts (8) The excitation dissociation process of molecules in electron-molecular conflicts (9) The excitation dissociation process of water atoms in electron-molecular conflicts (9) The excitation dissociation process of molecules in electron-molecular conflicts (9) The excitation dissociation process of water atoms in electron-molecular conflicts (10) The excitation dissociation process of water atoms in electron-molecular conflicts (9) The dependence of line shape and angle on line shape is analyzed correctly. The main excitation process of water atom formation is three times, and the value of water atom formation is 20.8, about 30, 3-5 - 40 eV, and the movement of water atom formation is 0 - 2, 3 - 5, 6 - 8 eV. In this case, the symmetry of the intermediate state is not equal to the symmetry of the intermediate state, but is equal to the symmetry of the intermediate state. In particular, the first component is not equal to 0.5%, and the intermediate state is equal to the life of the molecule. (2)Water and water molecules stimulate the formation of water atoms, and their dissociation into fractions is measured to determine the symmetry of the dissociation process. The first and third components of water have optical tolerance, and the second and fourth components have optical inhibition. Water element is the speed component of optical inhibition, water element is the optical tolerance component of optical inhibition. (3)Detailed analysis of the vibration structure of the electron impact molding of the blue film. In the same case, the optical tolerance is controlled by the vibration structure. The number of excitation levels is measured. (4)The measurement of electron impact properties of electron impact polymers. Light emission is now available in the 240 - 400 nm field, with a wide range, which is crucial to Si-So migration. 2. In order to provide a subsidy for the analysis of the dissociation process of molecules involved in the molecular conflict, the molecular conflict room, 6-inch chippings, and the oil-return port have been purchased, and the oil-dispersion port has been used in the existing hands. The assembly of the molecular conflict device has been implemented. Under the eyes of the right part of the adjustment.
