  Electromagnetic transitions involving nucleons and their resonances are here
presented in the fermionic sector of the AdS/QCD soft-wall model, using the
differential configurational entropy (DCE) as a measure of information entropy.
The DCE is employed to derive adjustable parameters that define the minimal and
nonminimal couplings in the nuclear interaction with a gauge vector field, in
the nucleonic $\gamma N \to N^*(1535)$ transition. The values obtained comply
with phenomenological data with good accuracy.
