Magnetic moment of 17Ne using β-NMR and tilted foil polarization

Abstract

We report on the measurement of the magnetic moment of the ground state of 17Ne. Radioactive 17Ne nuclei were delivered from the high resolution mass separator at ISOLDE onto a high voltage platform at −200 kV and were polarized using the tilted foil polarization method. The polarized nuclei were implanted into a Pt stopper situated in a liquid-helium cooled β-NMR apparatus and the asymmetry destruction of the ensuing β rays was monitored as a function of the rf frequency applied to the polarized nuclei. The measured value of μ = 0.74 ± 0.03 affirms the nature of the ground state of 17Ne and is compared to shell model calculations.
