  The electric field corrections to the recently measured muon magnetic moment
g-2 anomaly are considered from both the classical (BMT) and the quantum
mechanical (Dirac) viewpoints. In both views, we prove that the electric field
inducing the horizontal betatron tune does not renormalize the anomaly
frequency. With this result kept in mind, the experimental muon magnetic moment
anomaly is in closer agreement with standard model predictions than has been
previously reported.
