Outline of Annual Research Achievements

本研究においては，原始惑星系円盤環境における表面反応によるH, C, N, Oの化学反応生成物を同定するとともに，その反応速度・生成分子の官能基ごとの同位体依存性を実験により決定することを目的とし，平成26年度においては，多種の基板作成，表面反応装置の立ち上げ，XANES装置のためのミラー系の開発と，その第一段階としてのゾーンプレートによる結像型装置の立ち上げ，原始惑星系円盤における有機物反応モデルの基礎となる物理と化学の結合部分の完成を主たる目的とした．いずれも順調な進展をあげ，当初目的を達成した．
平成26年度は具体的には，第一に，各種基板作りとその生成物観察を系統的におこない，原始惑星系円盤条件を満足する非晶質珪酸塩，金属基板作成の最適条件を確定した．第二に，それを用いた表面反応実験を開始した．原始惑星系円盤条件で非晶質珪酸塩基板上では今のところ反応物は得られていないが，パラメータを変化させた系統的実験の継続中である．第三に，XANES装置において使用するゾーンプレートの作成をおこない，SPring-8内の装置に設置し，撮像をおこなった．その結果，想定した解像度を十分に達成することが判明した．他方，問題点として，波長固定においては高い解像度を得ることができるが，波長を変化させた場合はその度に光学系の調整が必要となり，ミラーのもつ利点とゾーンプレートの利点を両立させることが課題として浮上した．第四に，表面反応の理論的解析をおこなう第一原理計算を結晶質フォルステライトによりほぼ完璧におこなうことが可能となった．第五に，原始惑星系円盤進化の物理と化学を結合させるモデルにおいては，物理部分の枠組みが完成し，今後実際的なモデルに展開できる見通しがたった．班全体として，きわめて順調に計画が進展している．

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

装置開発，モデルなどのすべての内容において年度当初計画を超える順調な進展を見ている．特にXANES装置開発は，ゾーンプレートによるものが予定以上の成果をうみ，また，表面反応のモデル化も順調だが，吸着反応実験が，原始惑星系円盤条件では有機物合成が進行せず，やや高い圧力でのみ実験が成功している点を改善する必要があり，全体の判断としては②とした．

Strategy for Future Research Activity

ミラー開発は解像度を上げることが課題であり，100nm程度の空間分解能を実現するため照明部分の開発をおこなう．XANES装置は，そのミラーを組込み，さらに可視光変換画像検出器を開発し，各元素での撮像を実現することが次年度課題となる．触媒反応実験は非晶質ケイ酸塩において有機物が合成される条件，特に圧力の加減を明確にすること，また，昨年度明らかとなったFeとNiの量比による有機物合成率の違いを系統的に明らかとすることが必要である．有機物進化モデル開発においては，有機物と無機物すべての円盤内移動と円盤進化のを整合的に扱うことのできるモデルに進展させることが課題となる．
