| 摘 要： | 利用与延发质子符合的子核中已知的第一个２＋→０＋（基态）的γ跃迁来鉴别其β延发质子先驱核的方法已在实验中得到证实，并在兰州重离子加速器ＳＦＣ上用氦喷嘴快速带传输系统成功地合成与研究了沿Ｚ＝０．７４３Ｎ＋１１．６质子滴线分布的稀土区新β延发质子先驱核１３５Ｇｄ和１２１Ｃｅ．该鉴别方法在缺中子稀土区新核素合成中将具有很大的应用前景． It′s more and more difficult to synthesis and study new nuclei along the proton drip line by using on line isotope separator because of its low efficiency. A specific method of “p γ” coincidence measurement, using the known low lying “2+→0+(ground state)” γ transition of the “daughter” nucleus in coincidence with its β delayed proton, could increase the detection sensitivity ...

| Abstract: | It′s more and more difficult to synthesis and study new nuclei along the proton drip line by using on line isotope separator because of its low efficiency. A specific method of “p γ” coincidence measurement, using the known low lying “2+→0+(ground state)” γ transition of the “daughter” nucleus in coincidence with its β delayed proton, could increase the detection sensitivity ... |
