Abstract: General form of multichannel resonating group equation is derived from the variational principle for reaction channels with arbitrary particle number. Detailed formalism is elaborated for restricted version of two-channel reaction where the scattering channel is accompanied by 3-body, one due to breakup of a scattering product. Calculated differential cross sections for direct scattering ⁶Li(α, α)⁶Li shows an essential improvement with account of 3-body channel appearing from direct breakup of scattered ⁶Li. To obtain the necessary accuracy the calculation requires powerful computing technique.

Keywords: resonating group equations, multibody reaction channels, scattering, direct breakup, differential cross sections.
