[en] The research on the giant resonance of atomic nuclei taking the opportunity of the discovery of E2 giant resonance about 15 years ago has developed to the discovery of E0, E3 and E4 giant resonances, GT and MI resonances and others. The recent development seems to proceed toward the more basic understanding of the oscillation mode of atomic nuclei themselves through the research on giant resonance carried out so far. Taking the opportunity of the discovery of GT and MI resonances and others, the role of Δ nucleons in atomic nuclei has been actively discussed, and this is one of the good examples. In order to understand more comprehensively the behavior of nucleons in atomic nuclei and the nuclear force acting mutually on nucleons, it is effective to study on respective excitation modes after separating the response spectra of atomic nuclei into spin, isospin and exciting angular momentum. It is important also to search for a new excitation mode of atomic nuclei. In order to put the present status in order and to discuss the new direction of development about the giant resonance of atomic nuclei, the study meeting 'Giant resonance' was held on June 21 - 23, 1988 in the Nuclear Physics Research Center, Osaka University. In this report, the discussions and reports at the meeting are collected. (K.I.)
