## Description

- description: "表面電子分光法における電子の非弾性平均自由行程（IMFP）を簡便に計算するための手法として，簡易単極近似（SSPA）を導入し，その有効性について解説する．SSPAは，従来のPennによる単極近似（SPA）をさらに簡略化した手法である．SSPAに基づいてエネルギー損失関数（ELF）から計算したIMFPは，41元素においてFPA（full
    Penn algorithm）およびSPAによる結果と比較すると，300 eV～10 keVの範囲において良好な一致を示した．特に，分散式中の係数 \U0001D6FC
    を0.4167 とした最適化SSPA では，FPA との平均相対差が3% 以下であり，実用的にも十分利用可能である．また，MathematicaによるSSPA-IMFPの実装方法や分散式の係数の最適化計算の手順についても詳述し，読者が再現可能な計算環境についても解説した．"
