Comment on "On the realisation of quantum Fisher information"

Abstract
It is shown that calculation of the momentum Fisher information of the quasione- dimensional hydrogen atom recently presented by Saha et al (2017 Eur. J. Phys. {\bf 38} 025103) is wrong. A correct derivation is provided and its didactical advantages and scientific significances are highlighted.
