The ratios of the hyperfine interaction constants a'' and the nuclear g factors of the stable isotopes of antimony have been measured. From these measurements the hy perfine structure anomaly, defined as nspection. (W.L = (a/ sub 121//a/sub 123/)(g/sub 123/ g/sub 121/)--1, was found to be (--0.352 plus or minus 0.005)%. nspection. (W.L has its origin in the difference in the spatial distribution of the nuclear magnetic dipole for the two isotopes, which is related to the structure of the two nuclei. The experimental result is compared with theoretical values of nspection. (W.L based on a variety of nuclear models. The determination of a/sub 121//a/sub 123/ makes use of the electron nuclear double resonance technique (ENPOR) which is discussed in some detail. The sample used in the experiment was silicon dopod with antimony and the microwave resonances were observed at ~9000 Mc/sec at a temperature of 1.2 deg K. The ratio of the nuclear g factors was determined by conventional nuclear magnetic resonance techniques. (auth)
