Title: Multipulse sequences in electron-spin echoes

Abstract

A method is described whereby Carr--Purcell (CP) multipulse sequences may be generated at a rate rapid enough for electron-spin echoes ESE and in a manner consistent with constraints of typical ESE spectrometers. Both Carr--Purcell--Meiboom--Gill and alternating phase-CP sequences may be produced. It is shown how such sequences may be utilized (1) to increase the rate of data collection, which is especially important in laser photo-induced experiments, and (2) to study slow motions. They are respectively illustrated with results on transient spin-polarized photoelectrons and electrons trapped in irradiated quartz.
