为了论证重离子束诱导反应超核能谱的可行性，在GSI进行了以2AGeV的~6Li弹丸在碳靶上进行的HypHI 0相实验。目前的数据分析表明，在p+π−(Λ)、3He+π−(3ΛH)和4He+π−(4ΛH)的不变质量分布中出现了峰，并推导了相应峰的寿命，与已知的值符合得很好。
The HypHI Phase 0 experiment with6Li projectiles at 2AGeV on a carbon target has been performed at GSI in order to demonstrate the feasibility of hypernuclear spectroscopy with induced reaction of heavy ion beams. Current data analyses have shown peaks in invariant mass distributions of p + π−forΛ,3He+ π−for3ΛH and4He + π−for4ΛH. Lifetime values for the corresponding peaks have been also deduced, which are in good agreement with the former known values.
