摘要： 循环场技术(Field-Cycling Technique)被成功地用于核四极双共振来测量晶体中的缺陷,大大提高测量的灵敏度,并用来测量Li3N中的缺陷.缺陷的四极能级劈裂和双共振的过程在文中进行了分析.文末对测得的Li3N的吸收线进行了扼要的讨论.

Abstract: Field-Cycling-Technique has boon successfully used for nuclear quadrupole double-resonance to investigate imperfections in crystals, to raise the sensitivity of the measurements and to measure the imperfections in Li3N. Quadrupole splittings of the imperfections and the double-resonance process are analyzed in this paper. At the end of this paper, a brief discussions is given to the measured absorption lines of Li3N.
