Hyperbolic form factors for Yukawa interactions, and applications to the Earth

Abstract We define the hyperbolic form factor of a density distribution as its bilateral Laplace transform, related by duality or analytic continuation to its ordinary form factor. For a sphere it is given by $$\Phi (x \!= \! kR) =\langle \,\cosh \,\vec k.\vec r\,\rangle = \langl...
