摘要
用ESR分析了天然方解石(CaCO_3)中的杂质Mn^(2+)离子和天然顺磁缺陷的性质。有关谱的理论计算基本和实验结果一致.解释了热处理和辐照样品出现的一些实验现象,最后提出了如何克服干扰解决含有一些杂质Mn^(2+)离子样品的定代问题。
The properties of Mn2+ ions and the signal of the defect used in dating for natural calcite were analysed by ESR. Theoretical calculation agrees satisfactorily with experimental results on ESR spectra. Experimental phenomena in the heat treatment and the irradiation of the sample were explained. A method is proposed to overcome the interference from impurities of Mn2+ ions in the sample.
