Abstract

Electron spin resonance has been observed in small particles of gold with a mean dia- meter of 30 A. The resonance is attributed to conduction electrons in particles where the electron-phonon interaction is severely inhibited. The mean g-value is 2.26 ± 0.02 and the mean line width 200 G. A variation of line width with temperature has been observed and is explained tentatively in terms of the discreteness of the electron energy levels.

金小颗粒中的传导电子自旋共振
在平均直径为30a的小金颗粒中观察到电子自旋共振。共振归因于电子-声子相互作用被严重抑制的粒子中的传导电子。平均g值为2.26±0.02,平均谱线宽度为200g,谱线宽度随温度变化,并初步用电子能级的离散性解释了谱线宽度的变化。
