The copper content of some geological samples has been determined by thermal neutron activation and subsequent coincidence gamma-spectrometry, taking advantage of the 180 degrees annihilation quanta of (64)Cu. By this means the interference of (24)Na, which is often the major gamma-activity induced in geological materials, is greatly reduced. The method is precise to about +/- 5 %, and the error is of the same order. The method should be especially attractive for application to samples with a copper content of 100-1000 ppm.
利用（64）铜的180度湮没量子，通过热中子活化及后续的符合伽马能谱法测定了一些地质样品中的铜含量。通过这种方法，通常在地质材料中诱导产生的主要伽马活性物质（24）钠的干扰被大大降低。该方法的精确度约为±5%，误差也在同一数量级。该方法对于应用于铜含量为100 - 1000 ppm的样品应该特别有吸引力。
