We investigate breakup dynamics in 6Li elastic scattering on heavy targets (T = 209Bi or 208Pb) near the Coulomb barrier energy. Since the subsystem of 6Li has a bound state as deuteron (n + p = d), a four-body channel (6Li + T → n + p + α + T) and a three-body channel (6Li + T → d + α + T) get entangled during scattering as a breakup channel. Both channels are precisely treated with the four-body version of the continuum-discretized coupled-channels method (four-body CDCC). Four-body CDCC well reproduces measured elastic cross sections with no adjustable parameter. We then estimate the channel coupling effects by dividing the breakup channel into fourand three-body channels. It is found that 6Li breakup is mainly induced by a three-body channel.
