摘要
本文介绍了从^(12)C离子轰击过的铀靶中用α-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6×10~5Pa/cm^2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。
The technique of a-hydrohyisobutyric acid concentration gradient elution and pressurized ion exchange chromatography was described for the rapid separation of rare earth elements (La, Ce, Pr, Nd, Sm, Eu, and Y) in 12C-induced fission of 238U at the room temperoture (≥20℃) and the pressure of about 6×105 Pa/cm2. The yields of 7 fission products were determined.
