  In general case of deformed Heisenberg algebra leading to the minimal length
we present a definition of the square inverse position operator. Our proposal
is based on the functional analysis of the square position operator. Using this
definition a particle in the field of the square inverse position potential is
studied. We have obtained analytical and numerical solutions for the energy
spectrum of the considerable problem in different cases of deformation
function. We find that the energy spectrum slightly depends on the choice of
deformation function.
