提出了一种仅适用于金属的极化核的新方法。结果表明，如果传导电子的电子自旋共振饱和，则原子核将被极化到与旋磁比为电子自旋的旋磁比相同的程度。这种作用是由电子和核自旋之间的超精细结构相互作用发生的顺磁弛豫过程产生的。对于大量的极化，由于相同的相互作用，电子自旋共振会发生偏移，并且应该提供极化程度的直接指示。
A new method for polarizing nuclei, applicable only to metals, is proposed. It is shown that if the electron spin resonance of the conduction electrons is saturated, the nuclei will be polarized to the same degree they would be if their gyromagnetic ratio were that of the electron spin. This action results from the paramagnetic relaxation processes that occur by means of the hyperfine structure interaction between electron and nuclear spins. A shift of the electron spin resonance due to the same interaction will occur for large amounts of polarization and should provide a direct indication of the degree of polarization.
