Description michel.maire 2015-12-14 17:50:08 CET 
Created attachment 370 [details]
output of Hadr03

in attachment, an output of Hadr03 showing that excited ions are explicitly created in inelastic collisions.
The physics is binary cascade (QGSP_BIC_HP).

A primary of 30 Mev is passed directly to pre-compound/de-execitation.

Hi Michel,

the problem has been fixed and the fix will be available in the next patch.
The reason of the problem - in the case of heavy isotopes internal conversion ismay be chosen during sampling but is forbidden by energy, now this situation does not stop the cascade, instead a small energy non-conservation appears. The past solution was used in previous version of de-excitation code.
