Soviet Physics Journal Aims and scope

Abstract

This paper considers the forming of nuclear induction signals upon their excitation by a periodically repeated series of two resonance RF pulses. The expressions obtained for the signals explain the regularities in the observed effects.

Additional information

Free induction and echo are possible only in nonequilibrium spin systems. Here the term “nonequilibrium” is used to characterize the state of a system previous to its excitation by induction or echo.
