{"Image DocumentName": "On-Line NMR/ONNuclear Magnetic Resonance on Oriented Nuclei is done at ~10 mK temperatures.", "Image ImageDescription": "Polarised radioactive nuclei are exposed to an RF field of variable frequency. When the Zeeman splitting frequency is found resonant absorption changes the. sublevel populations and hence also the observed anisotropy a resonance in the. anisotropy versus frequency plot. By cooling an ensemble of atomic nuclei down to mK temperatures in presence of a strong magnetic field, nuclei can be oriented. Their spins show a preferential direction with respect to magnetic field. The study of the angular distribution of the radiation emitted by these oriented nuclei yields information on the structure of the decaying nuclei like: spins, multipole and parity mixing. The nuclei are placed in a radiofrequency field the frequency which is slowly varied. When the frequency matches the nuclear sublevel Zeeman splitting resonant absorption changes the sublevel populations and hence also the observed anisotropy. This gives rise to a resonance in the anisotropy of gamma-ray angular distribution versus RF frequency . With the NMR technique we are able to find the g-factor and the nuclear magnetic moment of the state emitting the gamma radiation. 87.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
