Related Articles Detection of (3)He spins with ultra-low field nuclear magnetic resonance employing SQUIDs for application to a neutron electric dipole moment experiment. J Magn Reson. 2008 Sep 17; Authors: Savukov I, Matlashov A, Volegov P, Espy M, Cooper M The precession of (3)He spins is detected with ultra-low field NMR. The absolute strength of the NMR signal is accurately measured and agrees closely with theoretical calculations. The sensitivity is analyzed for applications to a neutron electric dipole moment (nEDM) fundamental symmetry experiment under development. PMID: 18835204 [PubMed - as supplied by publisher] ...
