摘要

本文介绍了从

C离子轰击过的铀靶中用

-羟基异丁酸浓度梯度和加压离子交换色层淋洗技术，在常温和约6×10

Pa/cm

压力时，在8h内分离了La、Ce、Pr、Nd、Sm、Eu和Y7个元素，并测定了它们的裂变产额，与其它核素的裂变产额一起构成了裂变碎片的质量分布曲线。

Abstract

The technique of

-hydrohyisobutyric acid concentration gradient elution and pressurized ion exchange chromatography was described for the rapid separation of rare earth elements (La

and Y) in

C-induced fission of

238

U at the room temperoture (≥20℃) and the pressure of about 6×10

Pa/cm

. The yields of 7 fission products were determined.
