Extracting information about few-body breakup thresholds from high-energy collisions

We show that the analysis of high-energy collisions provides an alternative, and sometimes advantageous, method of gathering information on a breakup system at threshold. We demonstrate the applicability of this approach by extracting the s-wave scattering length a0 for the collision of electrons by...
