Abstract:  The breakup and knockout reactions at intermediate and high energies are of the advantages such as simple reaction mechanism， sensitive to the surface of the nucleus， mature theoretical treatment and so on， and therefore have been applied successfully to the study of exotic structure of unstable nuclei. In order to deal with the problems of the secondary beam which often has large beam spot size and energy spread， the special experimental methods and techniques， such as inverse kinematics complete detection， combining light and heavy targets， high resolution dispersionmatch magnetic spectrometer， forward neutron spectrometer， inbeam γ spectroscopyetc， have been developed and applied over the time， allowing much improved detection capability and sensitivity. This report gives an overview of the progress made with the breakup and knockout reactions for unstable nuclei study， based essentially on the new physics explored and the evolution of the experimental method applied. Possible future developments are also discussed.
