High Energy Gamma Experiments at HIRFL and CSR

Key words: 
• giant dipole resonance /
• Bremstrahlung /
• double phonon state

Abstract: The experiments on giant dipole resonance performed at HIRFL of the Institute of Modern Physics are reviewed. At HIRFL and CSR the prospective high energy gamma experiments on double phonon state, Bremstrahlung, the connection between disappearance of collective motion and phase transition, and so on, are also discussed.
