| contents | We study the two dimensional system influenced by a non-central potential consisting of a Kratzer potential with a dipole moment, along with a vector potential of the Aharonov-Bohm (AB) effect. We explore various information theoretic measures, including Fisher information, Shannon entropy, Tsallis entropy and Renyi entropy. our numerical results show that the Fisher information increases with an increase in dissociation energy and decreases with rinsing dipole moment, AB potential strength, and both radial and angular quantum numbers. In contrast, the Shannon entropy, the Tsallis entropy and the Renyi entropy decrease with rising dissociation energy, while they increase with an increase in dipole moment, AB potential strength, as well as radial and angular quantum numbers. These observations collectively indicate that both precision and localization of particles in space are enhanced by the increasing of the dissociation energy while they are reduced when we increase the dipole moment, the AB potential strength, and both the radial and angular quantum numbers. |
