The HypHI project: Hypernuclear spectroscopy with stable heavy ion beams and rare isotope beams at GSI and FAIR
摘要:
HypHI合作旨在使用GSI和fAIR的稳定重离子束和稀有同位素束进行精确的超核光谱学,以研究极端同位旋的超核,特别是富中子超核,以了解富中子介质中的超子-核子相互作用,以及超核磁矩,以研究核中的重子性质。我们目前正在准备第一个实验,在2 AGeV的$^6$ Li和$^{12}$ C束,以证明通过识别$^{3}_Λ$ H,$^{4}_Λ$ H和$^{5}_Λ$ He精确超核光谱的可行性。关于这些超核的第一次物理实验计划于2009年进行。在本文件中,将讨论HypHI项目的概述和第一次实验的细节。
英文摘要:
The HypHI collaboration aims to perform a precise hypernuclear spectroscopy with stable heavy ion beams and rare isotope beams at GSI and fAIR in order to study hypernuclei at extreme isospin, especially neutron rich hypernuclei to look insight hyperon-nucleon interactions in the neutron rich medium, and hypernuclear magnetic moments to investigate baryon properties in the nuclei. We are currently preparing for the first experiment with $^6$Li and $^{12}$C beams at 2 AGeV to demonstrate the feasibility of a precise hypernuclear spectroscopy by identifying $^{3}_Λ$H, $^{4}_Λ$H and $^{5}_Λ$He. The first physics experiment on these hypernuclei is planned for 2009. In the present document, an overview of the HypHI project and the details of this first experiment will be discussed.
