摘要：
A method and an apparatus for detecting the existence of a specific substance in an article to be inspected in which an electromagnetic wave having energy in the vicinity of transition energy between spin states of an atomic nucleus applied with energy splitting due to electrostatic interaction between said atomic nucleus in the specific substance and an electric field in the substance which is peculiar to said specific substance is irradiated to the article to be inspected, thereby detecting transition between said spin states.
