Giant resonances are collective excitations of the nucleus in which a large fraction of the component nucleons are set into coherent modes of vibrations. Exotic excitations like the double giant dipole were predicted for many years but not observed experimentally until recently. Several experiments have been carried out at Los Alamos National Laboratory to search for these new collective modes of the nucleus. The results discover two previously unobserved types of double giant resonances. This work presents the recent pion double charge exchange data and the analysis that support the existence of two such exotic vibrational nuclear modes. Multiple excitations of the giant dipole resonance using relativistic heavy ion excitation is under investigation. The results from pion double charge exchange excitation will be compared with the relativistic heavy ion scattering.
