On Green's functions for Hamiltonians with potentials possessing singularity at the origin: application to the zero-range potential formalism

Sergey L. Yakovlev, Vitaliy A. Gradusov

We evaluate the short-range asymptotic behavior of Green's function for a Hamiltonian when its potential energy part has an inverse power singularity at the origin. The analyticall…
