Description
The observation of features, often referred to as "Wigner cusps" in a scattering cross section at the opening of a new scattering channel has been widely reported in electron scattering, and has been attributed to strong coupling between the two scattering channels. Recently a series of cusps were observed in positron scattering from the noble gases [A. C. L. Jones, Phys. Rev. Lett. 105, 073201 (2010)10.1103/PhysRevLett.105.073201]. In this case, the strong opening of the positronium formation...[Show more]
