Abstract

Nuclear magnetic resonance measurements were carried out on neutron activated ²⁰F(T_1/2 = 11 s) nuclei in a single crystal of KZnF₃. The quadrupolar splitted NMR spectrum, detected via the ²⁰F β -radiation asymmetry, could be observed using a radio frequency modulation technique. The quadrupole coupling constant was determined to e²q Q/h= + (12.0 ± 1.5) MHz at room temperature. The sign of e² q Q was obtained from a simultaneous γ-ray anisotropy measurement on the succeeding ²⁰Ne transition. Utilising a calculated field gradient of the fluorine atom, an fq=4.6% is determined. This value is compared with literature data of similar compounds.
