Abstract
Collisions of deformed uranium nuclei provide a unique opportunity to study the spatial dependence of charmonium in-medium effects. By selecting the orientations of the colliding nuclei, different path lengths through the nuclear medium could be selected within the same experimental environment. In addition, higher energy densities can be achieved in U + U collisions relative to Au+Au collisions. In this paper, we investigate the prospects for charmonium studies with U + U collisions. We discuss the effects of shadowing and nuclear absorption on the $J/\ensuremath{\psi}$ yield. We introduce a new observable which could help distinguish between different types of $J/\ensuremath{\psi}$ interactions in hot and dense matter.
