Mutual R\'enyi information for two disjoint compound systems
  The leading term for the mutual R\'enyi information is studied for two widely separated identical compound systems for free scalar fields in $(d+1)$ Euclidean space. The compound system consists of two identical spheres in contact, with a result consistent with a universal form for the leading term for the mutual R\'enyi information.
