On a formula of Braun and Rebane for variational bounds to overlap |
|
| Authors: | F Weinhold P S C Wang |
| Abstract: | A recent formula of Braun and Rebane for variational bounds to overlap is shown to be closely related to the methods of Rayner and of Weinhold for the same problem, and is extended to give upper and lower bounds to overlap in both ground and excited states. |
