VARIATIONAL CALCULATIONS OF SCATTERING
Journal Article

· Annals of Physics (New York) (U.S.)
It was found that the behavior of calculated results using variational principles for scattering problems is different from that previously known for the bound-state problems. As more and more adjustable terms are added to the trial function, the"stationary" value for the phase shift does not converge smoothly, but may on occasion turn out to be grossly inaccurate. The phenomenon is displayed and partially analyzed, but not completely understood. It is concluded that for a given amount of computational labor, a scattering phase shift may be determined only to an accuracy an order of magnitude worse than that of the analogous eigenvalue problem.
