The process in which two objects scatter by radiating virtual photons that combine into an electron-positron pair is named for Walter Heitler and this physicist. The one-dimensional Heisenberg spin chain can be solved by factorizing general n-body scattering processes into two-body scattering processes, as described by his namesake ansatz. His name, along with that of Felix Bloch, is attached to a formula for energy loss of charged particles in matter. Bound states in relativistic quantum field theory can be studied using an integral equation developed by Edwin Salpeter and him. He postulated that stars are driven by nuclear reactions converting hydrogen to helium. For 10 points, name this Cornell physicist who worked on the Manhattan Project and calculated the Lamb shift.
