论文摘要
预测高三体具有较小的结合能（加权平均约为150 keV），与大物质半径（〜10 fm）一致，比35年前发现的历史11LI光环大。但是，高三体的结合能的实验值范围为70至400 keV。在这项工作中，我讨论了大三体的电磁响应和相互作用半径以及高能量重离子碰撞（〜1-2 GEV/核子）如何有助于确定其大小和结合能的更高准确性。
The hypertriton is predicted to have a small binding energy (a weighted average of about 150 keV), consistent with a large matter radius (~ 10 fm), larger than the historical 11Li halo discovered more than 35 years ago. But the reported experimental values of the binding energy of the hypertriton range from 70 to 400 keV. In this work I discuss the electromagnetic response and interaction radius of the hypertriton and how high energy heavy ion collisions (~ 1 - 2 GeV/nucleon) can help achieving a higher accuracy for the determination of its size and binding energy.
