PADE APPROXIMANT STUDIES OF LONG RANGE FORCES,

Abstract

Two-point Pade approximants of the dynamic polarizabilities are used to calculate the leading term of the long range (van der Waals) force between atoms. The bounding properties of these approximants are explicitly established. A successive approximation procedure is introduced. It keeps each step simple and makes the higher order approximation expressible in closed forms and readily applicable. The results of hydrogen and noble gases show that, with the known moments, the present method gives the tightest upper and lower bounds yet established. (Author)
