Abstract

The quadrupole moment of light nuclei 17F in the ground state (I?= 5/2+) is measured by the ?-NMR method. The effective charge of the last proton in a d5/2orbit for 17F is extracted from the measured quadrupole moment Q(17F) divided by the quadrupole moment Qspcalculated with a single particle model. A proton effective charge of eeffp= 1.12 ± 0.07eis obtained, which is in agreement with that given by a particle-vibration coupling model calculation within the experimental error. The present value of the proton effective charge is strong evidence for the existence of a proton skin in 17F (I?= 5/2+). [ABSTRACT FROM AUTHOR]

Abstract

The spin polarized β-emitting nuclei12B ( I π=1+, T 1/2=20.18 ms) were produced by the nuclear reaction11B(d, p)12B and by the selection technique of the incident deuteron energy and the12B recoil angle following the nuclear reaction. The nuclear magnetic moment of the short-lived nuclei12B was measured by β-NMR with the β-NMR and β-NQR setup established for the first time in China. The nuclear magnetic moment of12B was determined to be μ=0.99993±0.00048 nm or g=0.99993±0.00048 after the precise correction of the Knight shift. [ABSTRACT FROM AUTHOR]
