Integral Hellmann-Feynman theorem as a criterion of the quality of wave functions of atomic-molecular systems

It is proposed to use the integral Hellmann-Feynman theorem for the quality control and refinement of atomic and molecular wave functions. Its validity is verified for variational wave functions of the positronium ion e+e−e−, the negative ion of the hydrogen atom p∞+e−e− (H−), and mesomolecules μ−π+...
