摘要：

The magnetic moment of Be-11 (T-1/2 = 13.8 s) was measured by detecting nuclear magnetic resonance signals in a beryllium crystal lattice. The experimental technique applied to a Br-11(+) ion beam from a laser ion sourer includes in-beam optical polarization implantation into a metallic single crystal, and observation of rf resonances in the asymmetric angular distribution of the beta decay (beta-NMR). The nuclear magnetic moment mu(Be-11) = -1.6816(8) mu(N) provides a stringent test for theoretical models describing the structure of the 1/2(+) neutron halo state.
