Description
ここで、eは素電荷であり、Zは原子番号であり、NAはアボガドロ定数であり、ε0は誘電率を表し、Aは原子量であり、Eは入射電子ビームのエネルギであり、ρは試料フィルムの密度を表している。この式は、L.Reimer著「電子顕微鏡の走査(Scanning of electron microscopy)」、Springer Verlag、第2版、1998年10月、138ページから引用したものである。この式は、後方散乱電子の収量ηが、Z、並びに試料フィルム密度ρの関数であることを示している。従って、後方散乱電子の収量ηをフィルム厚dの関数として測定するだけでは、厚みdの変化をZ及び/又はρの変化をもたらす組成変化から区別することができない。
