The paper gives some background about prewar studies of paramagnetic relaxation, the author's postwar measurements of paramagnetic relaxation using 3 cm microwaves, the beginning studies of alkali metal NMR at Illinois, Overhauser's arrival and proposal, the discovery of the ESR of conduction electrons, the experiment confirming his idea in Li and Na metals, then in solutions of Na atoms in liquid ammonia, and the realization that a form of Overhauser effect might be seen when several isotopes were present in cases where atoms were mobile. Two other experiments at Illinois inspired by the Overhauser experiments are briefly described: measurement of the spin susceptibility of conduction electrons and measurement of spin-lattice relaxation times in superconductors.
本文介绍了战前顺磁弛豫研究的背景,作者在战后使用 3 厘米微波进行顺磁弛豫测量的情况,在伊利诺伊州开展碱金属 NMR 研究的开端,奥弗豪泽尔的到来和建议,传导电子的 ESR 的发现,在 Li 和 Na 金属中证实他的想法的实验,然后在 Na 原子在液氨溶液中的实验,以及当存在多个同位素且原子处于移动状态时可能会出现奥弗豪泽尔效应的认识。伊利诺伊州的另外两个受奥弗豪泽尔实验启发的实验也进行了简要描述:测量传导电子的自旋磁化率和测量超导体的自旋晶格弛豫时间。
