The J-matrix reproducing kernel: Numerical weights at the Harris energy eigenvalues
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...

A fully crossing symmetric vertex function
A fully crossing symmetric vertex function was calculated in an exactly soluble model. It has branch points in the interaction strength whose positions are independent of the energy variables. The irr...

Scattering by the Coulomb plus Graz separable potential is studied by employing a coordinate space approach to the problem. Exact analytical expressions for on- and off-shell Jost functions fl(k) and fl(k,q) are constructed and certain useful checks are made with regard to their limiting behavior and on-shell discontinuity.
