Phys. Rev. Lett. 82, 497–500 (1999)Magnetic Moment of the 1- Ground State in 18N Measured with a New β Level Mixing Nuclear Magnetic Resonance TechniqueReceived 27 August 1998; published in the issue dated 18 January 1999 The 18N ground state magnetic moment |μ| = 0.135(15)μN has been measured using a modified β nuclear magnetic resonance technique. The value is compared to shell-model calculations. Spin-aligned 18N projectile fragments were produced in the fragmentation of 22Ne at 60.3 MeV/nucleon. Polarization of the nuclear spins was resonantly induced by a combined magnetic dipole, electric quadrupole, and radio frequency interaction. This is the first application of a new method that allows production of polarized nuclei from spin-aligned projectile fragments, allowing one to measure β asymmetries. The method opens a new range of applications to study static dipole and quadrupole moments of exotic nuclei near the drip lines. © 1999 The American Physical Society URL:
