摘要
分析了Ａ＞１７０质量区丰中子核素的产生、分离和鉴别过程，总结了在这一质量区用较轻中能重离子炮弹打重靶产生新核素的优点．提出了在在线同位素分离器上使用带有优良元素选择性的激光离子源和多层靶加气体传输系统的改进措施．
The production, and process of separation and identification of new neutronrich nuclei with mass number A>170 were analyzed. The advantages of producing new isotopes in this mass region by lighter heavy particles on heavy targets were summarized. It is put forward an improvement method that a laser ion source and multilayer target combining with gas jet transport method can be used on online isotope separator.
