Resonant scattering experiments with RI beams were performed for studying two-nucleon correlation. In the 9Li+ d experiment, we searched for an analog resonance corresponding to the two-neutron halo nucleus 11Li(=9Li+ 2n), and no resonance peak was observed. However, there remains a possibility of a wide resonance below the experimental lower energy limit of 0. 3 MeV. In the 17Ne+ p experiment, a new 18Na resonance(excited state) was found. It is suggested that the state does not contribute to the two-proton decay of 19Mg.

为了研究双核子关联，进行了RI束共振散射实验。在9 Li + d实验中，我们寻找了对应于双中子晕核11 Li（= 9 Li + 2n）的类似共振，没有观察到共振峰。然而，仍然有可能在低于实验能量下限0。3兆电子伏。在~（17）Ne + p实验中，发现了一个新的~（18）Na共振（激发态），它对~（19）Mg的双质子衰变没有贡献。
