摘要
The method of Padé approximants is worked out numerically for the case of a Yukawa potential to find bound states and resonances. The calculation is performed to the sixth order of the perturbation series. An interesting result about the unitarity properties of non-diagonal approximants is proved. Some insight can be obtained in the way this method works in relativistic field theory, especially in connection with left-hand singularities. © 1969.
