Abstract
We report on the application of N-14 electron nuclear double resonance (ENDOR) at 8.5 T and 239 GHz (lambda=1.2 mm) in a gamma-irradiated be taine arsenate single crystal. A laser was used as a far-infrared radi ation source in a transmission-type electron paramagnetic resonance (E PR) setup without a cavity. The four expected nitrogen ENDOR lines wer e observed, but due to insufficient saturation of the EPR transitions the signal/noise ratio was not larger than 10 and the signals vanished at temperatures above 20 K.
