Abstract：
A quark model calculation for the short-range contribution in the pion double-charge-exchange (DCX) reaction is presented. In the framework of this new model, the angular distributions of ¹⁸O(π⁺, π^-)¹⁸Ne(g.s.) at low energies are calculated and compared with the experimental data. It shows that this model can explain the "anomalous" increasing behavior for the DCX reaction around 50 MeV quite well.
