Abstract

We discuss the phenomenon of multiple spin echoes induced by tipping angle-dependent frequency shifts. A general expression for the echo amplitudes neglecting diffusion effects is given as a spatial integral over a periodicity interval. The asymptotic behavior of this formula in the limit of many echoes is discussed and compared with the exact solution and experimental results.
