摘要

在堆中子活化分析中，1975年A. Simonits

[1]

等人提出了单比较器

值方法，继后陆续发表了很多文章。F. De Corte

[2]

、A. Simonits

[3]

、L.Moens

[4]

等人对此进行了深入细致的研究工作，他们分别在根特核科学研究所和布达佩斯物理中心研究所两家活化分析实验室进行了不同辐照条件及测量系统的实验，严格地评价

值

[5-6]

，报道了70多个核素的

0Au

值

[2，4]

，其精度好于2%。在国内，田伟之

[7]

、周云鹿

[8]

等人也对

值进行了一些初步的研究，其精度在2—10%，偏离理论值大部分在15%左右。为了逐渐完善单比较器方法，本工作从应用的角度出发，用（1）式将单比较器

值方法付诸于实验中多元素分析。

Abstract

-values of 23 nuclides used in monocomparator method of reactor neutron activation analysis have been measured. The accuracy is better than 4%. In the measurement

Zr-

Zr are used as flux monitor and

198

Au as comparator nuclides which are exposed to diferent irradiation conditions (31

115) in the HWRR of Institute of Atomic Energy. The concentrations of 20 elements in the standard reference materials 1632a

GXR-4 and BCR-1 have been analyzed using K

-method. The results are consistent with the values in literature within the extent of errors.
