The J-matrix reproducing kernel: Numerical weights at the Harris energy eigenvalues
Hashim A. Yamani · Journal of Mathematical Physics · 1984
The restriction of the J-matrix scattering wave function to the subspace where the potential is nonzero is used to define a reproducing kernel in the energy parameters. The values of the kernel at the positive Harris energy eigenvalues are shown to be related to the numerical weights at these eigenvalues.
