Magnetic Moment of F17 – Nuclear Magnetic Resonance by Polarization Following O16 (d, n) F17 Reaction –

The nuclear magnetic resonance of F 17 ( T 1/2 =66 sec) has been observed using the polarization of recoil nuclei produced by the reaction O 16 ( d , n ) F 17 and the β-decay anisotropy as the indicator of the polarization. The accomplishment of the experiment was essentially due to the persistence of the polarization by specific experimental methods, i.e. , the use of a strong magnetic field (\({}5\) kG) in the direction of polarization and the use of pure CaF 2 crystals as the stopping material of recoil ions. The observed asymmetry of β-counting was about 2% and a spin relaxation time T 1 comparable to the half-life of F 17 was observed. The value obtained of the magnetic moment of F 17 is µ=4.7224±0.0012 nm with the diamagnetic correction.
