| Abstract: | A Super-regenerative NQR Spectrometer has been described. The Super-regenerative oscillator constructed by field effect transistors works in wider frequency range and has higher sensitivity, The 35Cl and 37Cl NQR Spectra of Some shemical samples recorded with this spectrometer are shown in this paper, and the advantages of using field effect transistors for NQR are discussed. |
