在前人的实验结果中,86Sr的高自旋态信息很少,前人利用84Kr(α,2nγ)86Sr反应,得到的86Sr的自旋仅达13。本实验的目的在于建立86Sr核新的能级纲图,并进一步研究86Sr的高自旋态结构。本实验利用重离子融合蒸发反应82Se(9Be,5n)86Sr布居86S高自旋态,在HI-13串列加速器上产生9Be束,束流能量为40~53MeV,强度为2~4nA。实验用靶82Se同位素丰度为8.73%,靶
In previous experiments, the 86Sr spin-86Sr information is very few, the former 86Kr (α, 2nγ) 86Sr reaction, the resulting 86Sr spin only 13. The purpose of this experiment is to set up a new energy level outline of 86Sr nucleus, and to further study the high spin state structure of 86Sr. In this experiment, the heavy ion fusion evaporation 82Se (9Be, 5n) 86Sr resides in the 86S high-spin state, generating 9Be beams on the HI-13 tandem accelerator with a beam energy of 40-53 MeV and an intensity of 2-4 nA. Experimental target 82Se isotope abundance of 8.73% target
