Magnetic dipole moment of the helion as measured in helium-3 gas, a reference for NMR field calibration.
Sets how strongly the particle lines up in a magnetic field — the quantity behind NMR, MRI and precision spectroscopy. A negative sign means the moment points opposite to the spin. Its ratios to the Bohr and nuclear magnetons and to other particles' moments are listed beneath.
