 note = {Four coherent betatron oscillation modes induced by the beam-beam interaction we observed in the TRISTAN Main Ring (MR) during two e+ and two e− bunches colliding operation. These modes are extracted using a phase mixing technique and used for measuring beam-beam parameters. The luminosity, the coupling coefficient and the emittance are estimated from the observation. The emittance agrees with the expected value to within 15% accuracy.},
