摘要：
The delta (DELTA) excitations in nuclei induced by intermediate energy charge exchange reactions are analysed within the iobar-hole model. It is found that the DELTA-hole correlations mediated by the energy-dependent pi-exchange interaction of the spin longitudinal channel shifts the DELTA-peak position downwards in energy by approximately 30 MeV. The origin of this shift is explained in detail.
