Abstract
The possibility of constructing a spectrum analyzer on the basis of a radiooptical-resonance method is studied. The absorption spectrum of optically oriented orthohelium atoms, induced by a sequence of radio-frequency pulses, is compared to the radiofield spectrum. The results can be used in the development of high-resolution wide-range microwave spectrum analyzers.
