Abstract
The electric polarizability of the nucleon is calculated in the soliton approach to the Nambu--Jona-Lasinio model. We analyze the leading- contributions, as well as the effects of rotational corrections and - mass splitting. Our model prediction is substantially reduced compared to other soliton calculations, and is closer to the experimental value.
