A MODIFICATION OF BLOCK-WALKERS REACTION FIELD FOR A NONIDEAL DIPOLE

Block-Walker's reaction field derived from considering a distance-dependent relative permittivity for a point dipole in the center of a spherical cavity is modified for a non-ideal dipole directed along the radius vector. The reaction field energies of the non-ideal dipole for two special cases are compared with those of the point dipole in the center of the cavity. Thus, the validity of approximation of Block-Walker's reaction field is investigated.
