A method for solving few-body scattering equations is proposed and examined.The solution of the scattering equations at complex energies is analyticallycontinued to get scattering T-matrix with real positive energy. Numericalexamples document that the method works well for two-nucleon scattering andthree-nucleon scattering, if the set of complex energies is properly chosen.Comment: 6 pages, no figures, resubmitted to Prog. Theor. Phy
