摘要：

The pion charge exchange process C-13(pi+, pi-0) N-13(gs) is calculated with an extended nuclear wave function for the A = 13 system that includes configurations outside the 1 p-shell. A small amount of 2p-shell admixtures leads to an improved description of the experimental excitation function. We also find a strong sensitivity of the differential cross sections as well as asymmetry to contributions from higher shells.
