JLab E12 - 19 - 002实验计划在杰斐逊实验室C大厅测量³ΛH（Jπ = 1/2⁺或3/2⁺（T = 0））和⁴ΛH（1⁺）的Λ结合能。结合能测量的预期精度为|ΔB总 Λ| ≃ 70 keV。对这些轻超核进行精确的光谱分析将有助于解开³ΛH结合能小和寿命短的谜团，以及ΛN相互作用中的电荷对称性破缺问题。我们的目标是在2025年进行该实验。
JLab E12-19-002 Experiment is planned to measure the Λ-binding energies of 3ΛH [Jπ = 1/2+ or 3/2+(T = 0)] and 4ΛH (1+) at JLab Hall C. The expected accuracy for the binding-energy measurement is |ΔBtotal Λ | ≃ 70 keV. The accurate spectroscopy for these light hypernuclei would shed light on the puzzle of the small binding energy and short lifetime of 3ΛH, and the chargesymmetry breaking in the ΛN interaction. We aim to perform the experiment in 2025.
