Outline of Final Research Achievements |
A new type of hypernucleus with strangeness -2, ^12_Ξ Be, which is a bound state of a Ξ in a nucleus, was successfully observed in the (K^-, K^+) reaction. The experiment was performed at a kaon beam line in J-PARC by using an existing magnetic spectrometer called “SKS”. The obtained binding energy of the Ξ hypernucleus is larger than the values previously reported. It suggests that the Ξ-N interaction is strongly attractive. In addition, a magnetic spectrometer system called “S-2S”, which has about three times better energy resolution than the SKS, has been newly constructed.
