The new results on the inclusive double charge exchange (DCX) reaction 16O(π-,π+)X at incident kinetic energy T0=0.75 and 1.15GeV are presented. The data were taken without using Cherentov counters. The new DCX cross sections agree well with the old ones. Both the values are about an order of magnitude larger than the theoretical cross sections calculated for the standard sequential mechanism. Two other approaches wich seem to explain the discrepancy are also briefly reviewed. |
