摘要

A hybrid-emulsion experiment was conducted to study a double-hyperfragment event and to calculate the binding energies of double hypernuclei. The ⁶_λλHe hypernucleus constituting the lightest closed shell structure containing baryons was studied. The experiment was conducted at the KEK proton synchrotron using the 1.66 GeV/c separated laser beams. The experiment identified the sequential decay of the hypernucleus; and measured its mass and interaction energy. Results of the experiment showed that the λλ interaction was weakly attractive.
