摘要：
Results of recoil-corrected continuum shell model calculations are presented for He-4(pi, pi'p)H-3. The extremely large values of sigma(pi(+), pi(+)'p)/sigma(pi(-), pi(-)'p) are shown to be a result of neutron excitations which couple to outgoing proton channels. The large ratio will occur in regions where neutron excitations increase rapidly in a particular channel and, therefore, may be a signal for giant resonances.
