Resumen:
It is well known that a suggestive relation exists that links Schr¨odingers equation
(SE) to the information-optimizing principle based on Fishers information measure.
The connection entails the existence of a Legendre transform structure underlying
the SE. Here, we show that appeal to this structure leads to a first order differential
equation for the SEs eigenvalues that, in certain cases, can be used to obtain the
eigenvalues without explicitly solving the SE. Complying with the above mentioned
equation constitutes a necessary condition to be satisfied by an energy eigenvalue.
We show that the general solution is unique.
