Lower bounds to bound state eigenvalues
Journal Article
·
· Phys. Rev., C; (United States)
Whenever the residual potential is repulsive the introduction of Pade approximants into the Brillouin-Wigner perturbation expansion generates lower bounds to the exact eigenvalues. The method is extended to perturbation from a subspace and to singular repulsions.
