概要
- 論文の詳細を見る
A low frequency Zeeman modulation microwave spectrograph for observing hyperfine structure of atomic sodium has been constructed. It sexperimetal details and the principle of operation are given. The sensitivity of the spectrograph may be estimated like the Stark modulation spectrograph. Since the modulation frequency cannot be chosen so high as Stark modulation, the noise figure of the crystal detector is rather large, which might be over come if the source modulation were superposed.
