摘要
It is suggested that the dependence of the poles of the Padé approximants on the masses of the external virtual particles for an off-mass-shell scattering amplitude may be used in order to improve, by means of a variational principle, the determination of the bound states. © 1969 Società Italiana di Fisica.
