摘要: The very large electromagnetic dissociation (EMD) cross section recently observed by Hill, Wohn, Schwellenbach, and Smith do not agree with Weizsacker-Williams (WW) theory or any simple modification thereof. Calculations are presented for the reaction probabilities this experiment entire single double nucleon removal EMD data set. It is found that those few reactions where disagree, exceptionally large. This indicates WW valid these one must consider higher order corrections perhaps even a nonperturbative approach to quantum electrodynamics.
