Method and apparatus for determining the degree of polarization core pin polarized gases, in particular of the helium isotope · 3 · he and · 1 · · 2 · · 9 · xe

摘要

The invention relates to a method for determining the degree of polarisation (P) of a nuclear spin polarised gas, in particular 3He, 129Xe, in which the nuclear spin polarised gas is placed in a container, comprising determining the magnetic field Bd of the polarised gas by measuring the magnetic dipole field emerging therefrom and then determining from Bd the degree of polarisation of the gas.
