Nuclear Quadrupole Resonance of Antimony Isotopes in Solids

概要

Measurements of nuclear quadrupole resonances of antimony isotopes in solids have been made at a relative accuracy of about one part in 10^6. Detectors are superregenerative oscillators. Relative accuracy was achieved by measurement of two or three resonance frequencies in a very short time. For antimony trichloride the results were almost in agreement with Wang's data, but the resonant frequency v_5 of the Sb^<l23> isotope, was higher about 2.5 kc. This implies that the cedecipole coupling constant might not have an order of magnitude which leads to a definitely measurable amount. In antimony oxide the simultaneous measurement was more easy, since it has a small asymmetry parameter. In this case, the deviation of resonance frequencies from a multiple relation is very small. These results are discussed in terms of cedecipole interaction and thermal vibration.
