Optically pumped /sup 3/He NMR and the Bohr magneton

Water has limitations as an NMR substance for the highest accuracy nuclear magnetic resonance (NMR) magnetometry work. We have been developing the technology of high field optically pumped /sup 3/He NMR as a precursor to a measurement of /spl mu//sub h/(/sup 3/He)//spl mu//sub B/, and progress to date is reported.<<ETX>>
