We investigate the possibility to find the leptonic CP-violation by combining
the reactor experiment with the superbeam experiment without antineutrino
superbeam. We show also how much the sensitivity on CP-violating phase delta is
affected by the fact that we have not known the sign of Delta m^2_31.Comment: 4 pages, 5 eps-files, ws-procs10x7.cls, talk at the 32nd
