Query: Analysis of the interaction of an electron with radial electric fields
  in the presence of a disclination   We consider an elastic medium with a disclination and investigate the
topological effects on the interaction of a spinless electron with radial
electric fields through the WKB (Wentzel, Kramers, Brillouin) approximation. We
show how the centrifugal term of the radial equation must be modified due to
the influence of the topological defect in order that the WKB approximation can
be valid. Then, we search for bound states solutions from the interaction of a
spinless electron with the electric field produced by this linear distribution
of electric charges. In addition, we search for bound states solutions from the
interaction of a spinless electron with radial electric field produced by
uniform electric charge distribution inside a long non-conductor cylinder.
