Abstract Electron spin resonance spectra were stadied for pure single calcite crystals irradiated with fast neutrons in which extremely narrow lines (width approximately 0.1 gauss) with thermal relaxation times at liquid helium temperatures of several seconds were observed. Crystals irradiated with doses of 10<sup>17 </sup>, 10<sup>18</sup>, and 10<sup>19 </sup>fast neutrons became brownish in color, and the main features of the spectrum of the sample irradiated with 10<sup>17 </sup> neutrons were studied at 8700 Mc and 77 K; whereas H<sub>0</sub> was rotated in a plane normal to the c axis. The implications of the observations are discussed.
