For just a few seconds I wanted to answer your question by using a polyshape for the task.
A polyshpe would be perfect, if only this were a 2-d problem, and you wanted to solve it for circles. Or, if polyshapes worked in 3-d. Maybe next release, but sadly, things get significantly more complex when you work in 3-d. Having written code for the intersection, union, etc., of volumes in 3-d and above, I will attest to that.

Here is what i invented
ix1 = (xc1-x2).^2+(yc1-y2).^2+(zc1-z2).^2 < R2^2;
ix2 = (xc2-x1).^2+(yc2-y1).^2+(zc2-z1).^2 < R1^2;
Of course i prepared explanations and result picture
