• Ultracold neutrons
• Mercury atoms
• Magnetic moment
• Gyromagnetic ratio

The neutron gyromagnetic ratio has been measured relative to that of the Hg-199 atom with an uncertainty of 0.8ppm. We employed an apparatus where ultracold neutrons and mercury atoms are stored in the same volume and report the result gamma(n)/gamma(Hg) = 3.8424574(30).
