Properties of the isovector monopole and other giant resonances in pion charge exchange

Journal Article · · Phys. Rev. Lett.; (United States)
; ; ; ; ; ; ; ; ;
We present the energies, widths, and cross sections of the isovector monopole resonance in nuclei between /sup 40/Ca and /sup 208/Pb excited by the (..pi../sup + -/,..pi../sup 0/) reactions. We also give results for the giant dipole resonance. Both resonances exhaust the same substantial fraction of the cross section calculated in a random-phase, distorted-wave impulse-approximation model. No isovector quadrupole resonance was observed.
