異常透過

anomalous transmission

[目次：理論(電子の散乱／回折／結像)]

結晶性試料の厚さが厚くなると、平均より大きな吸収を受ける電子波は速く減衰するが、平均吸収より小さな吸収を受ける電子波は減衰が遅く大きな透過力を持つ。この現象を異常透過という。

When a crystalline specimen is thick, the electron wave that undergoes a larger absorption than the average absorption is damped rapidly; however the electron wave that undergoes a smaller absorption than the average absorption is damped slowly or has a greater transmissivity. This phenomenon is termed "anomalous transmission."
