Title: Partial-wave Coulomb t-matrices for like-charged particles at ground-state energy,
Abstract: We study a special case at which the analytical solution of the
Lippmann-Schwinger integral equation for the partial wave two-body Coulomb
transition matrix for likely charged particles at negative energy is possible.
With the use of the Fock's method of the stereographic projection of the
momentum space onto the four-dimensional unit sphere, the analytical
expressions for s-, p- and d-wave partial Coulomb transition matrices for
repulsively interacting particles at bound-state energy have been derived.
