The first one is the complex scaling approach. The second method is based on an immediate calculation of resonances as zeros of the three-body scattering matrix continued to the physical sheet.6 pages, Talk presented at the International Conference "Modern Trends in Computational Physics" (July 2000, Dubna, Russia)Computational Physicstext
