UDC 539.184.28; 621.375.4 The suppression of synchronous interference NQR Politanskii L. F., Samila A. P., Khandozhko V. À. Keywords: NQR, Zeeman modulation, synchronous interference, hexamethylenetetramine. The principles of frequency and Zeeman modulation in nuclear quadrupole resonance were considered, and the advantages of the latter were shown. The authors propose a method to eliminate the synchronous noise caused by switching of the magnetic field. Results of observations of the resonance line with 14N in the hexamethylenetetramine sample weighing 2 g were given. Ukraine, Yuriy Fedkovich Chernivtsi National University. |
