= Inversion of spherical Radon transform in a spherical shell =

We derive explicit inversion formulas recovering functions supported in spherical shells either inside a sphere or outside the sphere, from  spherical Radon transforms with centers on the sphere and with partial data in the radial direction. We present numerical simulations validating our inversion formulas.
