PROPOSALS AND PREDICTIONS FOR (e,2e) EXPERIMENTS ON HIGH-T_c CUPRATE OXIDES K.A.Kouzakov, Yu.V.Popov Nuclear Physics Institute, Moscow State University, Moscow 119899, Russia The possibilities of obtaining an information on electron states in the high-T_c cuprate oxides by means of (e,2e) spectroscopy are examined. The analisys is made beyond an interpretation of the spectra in the independent-particle approximation. For the low-energy electron states, (e,2e) spectroscopy is found to be similar to that of angle-resolved photoemission. The proposals are made how to observe the magnetic Brillouin zone in undoped materials and energy gap in superconducting materials.
