摘要：

A five-pulse electron-spin-echo sequence, (pi/2)y-tau-1-pi-y-tau-1-(pi/2)x-T-(pi/2)x-tau-2-pi-x-tau-2, is introduced. The modulation amplitude obtained with this new scheme can be up to a factor of eight larger than in the corresponding three-pulse experiment. The signal contains no unmodulated part. Extensions with further improved modulation amplitude are discussed.
