Nuclear statistics, microcanonical or canonical? The physicists vs. the   chemists approach
  Nuclei are small and inhomogeneous. Multi-fragmented nuclei are even more inhomogeneous and the fragments even smaller. System studied in chemical thermodynamics (CTh) consist of several homogeneous macroscopic phases. Evidently, macroscopic statistics as in Chemistry cannot and should not be applied. Taking this serious, fascinating perspectives open for statistical nuclear fragmentation.
