摘要
提出了核双电荷交换反应的双重子共振态的反应机制，成功地解释了长期以来一直困惑着人们的共振区反应的角分布的实验结果．说明了共振区核双电荷交换反应是寻找双重子共振态的一个可能的途径．
The dibaryon mechanism is suggested for Pion-Nucleus double charge exchange reaction. The calculations within this mechanism are performed for 18O
18 Negs reaction at the energy of 164MeV.The principal finding from this study is that
the dibaryon mechanism may exclusively be responsible for solving many long-standing
puzzles of 164MeV double charge exchange reaction on the target 18 O.
