    Notes: The model of an electron bound to an impurity (or to a core hole) and interacting with a boson field is analyzed in terms of bosonic variables symmetry adapted to the spherical symmetry about the impurity center. It is shown that the use of this appropriate set of variables considerably simplifies the solution of the variational problem based on a Lee–Low–Pines-type of ansatz for the ground-state variational wave function.
