Dynamic Nuclei Polarization

Concept: Spin ^= Angular Momentum Picture: Particle with SPIN, that rotates around its center of gravity Precise description: Only in the framework of quantum mechanics W. Pauli was against the picture of a rotating electron ”It took quite a while, until N. Bohr was successfully, to convince his very critical pupil (W. Pauli) from the ingenuity of this new concept.” (Phys.-Blätter, April 2000) e. g. for electron, proton, neutron (Spin 1/2 - particles) 2 discrete numbers in a magnetic field (orientation quantization, energy quantization) B-magnetic field Particles with Spin can be manipulated with magnetic fields (analogy: magnetic needle (compass) in the earth magnetic field)
Polarization = Orientation of Spins in a magnetic field Without magnetic field: Randomly orientated spins With magnetic field: Orientation of spin All Spins in magnetic field direction : 100 % Polarization Change of polarization (e.g. destruction by HF-field) = energy change in the spin system measured by the Nuclei Magnetic Resonance (NMR( NMR) ) method ⇒ resonance signal 6 Li D ⇒ ´visibility` of the particles with spin (mainly protons) by Magnetic Resonance Imaging (MRI)
