Outline of Final Research Achievements

The following results were achieved through this project. (1) A nanoscale isotopic mass spectrometer based on a new principle of post-ionisation was improved to obtain ion images with a spatial resolution of 100 nm. (2) A system that can simultaneously analyse elements with low to high concentrations was developed. (3) Using this system, simultaneous multi-element analysis of presolar particles extracted from meteorites in the range of m/z = 10-150 was carried out and signals were obtained. (4) Significant isotopic anomalies were detected, especially for Si, indicating an AGB star origin. (5) Pb isotope analysis on the order of ppm was possible with a spot size of 1 micron. (6) This enabled dating of smaller quantities of lunar samples than previously possible.

Academic Significance and Societal Importance of the Research Achievements

ポストイオン化を新機軸としたナノスケール同位体質量分析装置を改良し、100nmの空間分解能でイオンイメージを得ることに成功した。また、1ミクロンのスポット径でppmオーダーの鉛の同位体分析が可能になった。その結果、従来よりも微小な月隕石で年代を議論することが可能になった。本装置の妥当性をチェックするために東京大学のNanoSIMSを用いて、種々のアパタイトの鉛同位体分析を行なった。副産物的に小惑星イトカワの形成年代と衝突破壊年代の決定に成功した。Scientihic Reportsで発表した同論文のAltmetrics数は719に達し、学術的/社会的に意義のある研究となった
