Abstract
The hyperfine interactions of short-lived β-emitter 12B implanted into a CaB6 crystal have been studied by means of the β-NMR technique. An electric quadrupole splitting has been observed at room temperature from which an electric field gradient of q=−(1.34±0.05)×1021 V/m2 was determined. From the present result, it was found that the 12B nuclei are mainly implanted in the substitutional boron site.
