Gravitational analogues of Rutherford scattering are well-established in theoretical physics and orbital mechanics literature, describing how masses or charged bodies deflect in gravitational fields analogously to classical electrostatic scattering.
The claim asserts the existence of a gravitational analogue of the classical Rutherford atom/scattering. Multiple physics papers (e.g., [3], [6], [8]) explicitly investigate, model, and apply 'gravitational Rutherford scattering' and related orbital mechanics, fully supporting the claim. No papers refute it.
