1. Conclusion.
We studied the characteristic Shannon entropy and Fisher information for the screened Kratzer potential model in both the position and momentum spaces for ground state and first excited state in one dimension. From the numerical result, we observed negative value in the ground state for the Shannon entropy which is an implication of a high localization. Also, numerical values in the position space show a decreasing position that was complemented with an increasing position space and their sum validated the BBM entropic relation for the potential model. For Fisher information, the entropic uncertainty relation was validated and its behaviour showed an increase in the position space followed by a decrease in the momentum space. This increasing Fisher information is a consequence of an increasing localization and vice versa. Analytical expression of the expectation values in position and momentum were presented. The Heinsberg relation was validated and squeezing phenomena were also observed for certain values of the screening parameter.
