Research Abstract

本研究の目的は、研究代表者らが初めて開発した「分子座標系の電子運動量分光」の検出感度の改善を図り、様々な直線分子の分子軌道の形を運動量空間において三次元観測し、量子化学理論が予測する波動関数形との比較を行うことである。これにより、運動量空間という従来とは反転した視点からの電子状態研究、いわば''運動量空間化学''を展開する。
上記の目的に向けて、前年度までに整備した新規イオン検出器システムの開発の成果を踏まえ、本研究計画最終年度の今年度は、窒素分子の分子座標系電子運動量分光を行った。水素分子を対象とした従前のものと比較して、Signal/Background比の大幅な改善を達成した。また、得られた実験結果は、位置空間で分子軸方向により広がったσ型分子軌道が分子軸と垂直な方向に伸びた形で観測されるなどフーリエ変換の性質を反映した運動量空間特有の波動関数形を示すことが分かった。こうした研究成果は、波動関数の形そのものの視覚化を具現化したものと関連研究分野で極めて高い関心を集め、2010年夏に開催されたInternational Workshop on Frontiers of Electron Momentum Spectroscopy (IWFEMS2010)から招待講演として採択された。現在、当該分野で最高水準の雑誌であるPhysical Review Letter誌に投稿すべく、論文を執筆中である。
以上のように、本研究は所期の目的を達成することができた。
