Generalization of the Hellmann-Feynman Theorem to Gamow States

摘要

The Hellmann-Feynman theorem valid for the parameter dependence of bound states is generalized to the case of Gamow states using an appropriate definition of scalar products and expectation values with such states. The one-dimensional square well potential is considered as an illustrating example. 21 refs. (Atomindex citation 18:015244)
