## Description

- description: 軟X線領域における部分蛍光収率X線吸収微細構造（PFY-XAFS）分光法は、試料のバルク領域に関する情報を得る上で重要である。しかしながら、自己吸収効果はPFY-XAFSスペクトルの微細構造に歪みを引き起こす深刻な問題である。この自己吸収は平坦な表面では解析的に補正可能だが、粉末中の粒子のような任意形状では不可能である。本研究では、任意形状の試料を小さな箱（ボクセルと呼ぶ）に分割して自己吸収効果を計算するボクセル法を提案する。CoO単結晶、NiO基板上のLi₂CO₃薄膜、CoO粉末試料のO
    KエッジPFY-XAFSスペクトルを比較することで、ボクセル法の有効性とその利点・限界を検証する。
