    The electrostatic hexapole is a versatile device that has been used for many years in gas-phase experiments. Its inhomogeneous electric field has been employed for many purposes such as the selection of rotational states, the selection of clusters, the focusing of molecular beams, and molecular alignment as a precursor for molecular orientation. In the last few years, the hexapolar electric field has been demonstrated to be able to control the conformer composition of molecular beams. The key point is that conformers, where the component of the permanent electric dipole moment with respect to the largest of the principal axes of inertia is close to zero, require more intense hexapolar electric fields to be focused with respect to the other conformers. Here, we simulated the focusing curves of the conformers of 1-chloroethanol and 2-chloroethanol under hypothetical beam conditions, identical for all conformers, in a hypothetical and realistic experimental setup with three different hexapole lengths: 0.5, 1, and 2 m. The objective was to characterize this selection process to set up collision experiments on conformer-selected beams that provide information on the van der Waals clusters formed in collision processes.

    本研究の目的は量子力学的に記述される分子回転運動をレーザー光の照射により制御し、実験的に観測することである。特に偏向型の量子状態選別器と組み合わせて分子の初期状態を選別、さらに配向させた状態から出発する点が先行研究との違いであり、一酸化窒素のような異核二原子分子の分子回転をより明瞭に可視化することを目指す。
    本年度は実験の準備に相当する基礎的な工程を主に実行した。まずターボ分子ポンプのオーバーホールを含む測定を行うための真空系の整備を行い、実験に必要な真空度を達成した。真空度の悪化は直接、状態選別器の選別能の悪化に繋がるので非常に重要な点である。オーバーホール以前と比べて真空度はよくなっており、10^-8 Torr を達成している。以前はアンモニア分子でテストした記録があったので同じ分子を使い、状態選別器が十全に動作することを確認した。次に観測の肝となる極短パルスレーザーを真空槽に導くためのレーザー光路の設計と実装を行った。レーザー発振装置は地理的に真空槽から離れているため、補助光学台などを作成してレーザー光を通した。現在は偏光の調整などに課題を残しているが、簡易的には真空槽に到達しており、前述のとおりテストに使ったアンモニアのクーロン爆発フラグメントの観測に成功している。現在の観測は一次元的な飛行時間測定にとどまっているので、これを二次元画像観測に置き換える必要がある。翌年度の時間・予算の多くはこのためにつかい、本丸となる回転制御およびその観測の実験を行う。
