摘要：

The modifications of the electromagnetic coupling in the presence of a strong external magnetic field are further investigated. The case of non-vanishing momentum transfers and the induced anisotropy of space arc explicitly taken into account. We confirm the presence of directional terms showing an unusual linear dependence on the external field strength. These last terms overwhelm the expected logarithmic corrections and tend to reduce the effective coupling.
