Mainz "measurement" of the $E2/M1$ ratio in the $N-\Delta$ transition

Abstract

We comment on the recent Mainz "measurement" (PRL78 (1997) 606) of the $E2/M1$ ratio in the $N-\Delta$ electromagnetic transition. Analyzing the Mainz data using an effective Lagrangian approach, we find this ratio to be (-3.19$\pm$0.24)%.
