Adiabatic Rapidhyphen;Passage Experiments in Some Solids

摘要

Two types of adiabatic rapidhyphen;passage experiments are considered for measuring spinhyphen;lattice relaxation times in solids, and results are shown for calcium fluoride, stearic acid, and lithium stearate. Although rapidhyphen;passage experiments using a symmetrichyphen;sweep method give shorterT1values in the substances examined than do experiments using a sequence of two rapid passages spaced at varying times, the two values may be brought together by applying a correction to the symmetrichyphen;sweep results for possible failure to invert completely the magnetization in the fast passage. For calcium fluoride and stearic acid, recovery from saturation experiments were also done and theT1values obtained from these experiments agree very well with the relaxation times found by rapidhyphen;passage methods.
