An elusive difference between CDRX and Fragmentation has been discussed but, in my and others‘ opinion, the answers are hardly clear enough and convincing. Indeed, in both cases it is argued that...

Normally only two pronounced maxima (at 5to20 and 50to60 degs) are observed. I wonder whether the mentioned feature at about 30dg may be due to 1. Poor local diffraction (say in terms of CI), 2....

Except for particular HPT straining way, the minimum thickness of fragments separated by HABs is generally some MISTIC invariant (1000 b i.e. about 200 nm) regardless of deformation scheme. ...
