Created attachment 41 [details] kinematics lines of (n,alpha) reactions i am shooting 14 MeV neutron on 16O nuclei. If I look the (n,alpha) reaction and more especially the laboratory angle of emission of the alpha versus its kinetic energy, i find that the energy is always the same whatever the angle. This is seen for the various excited states also which are populated by this direct reaction. In case of 28Si nuclei, the direct reaction gives good result. The file F06 is there for 16O so i do not understand well even if i have to confess that i did not go inside the different class called during the process. Is it just because 13C data files are absent and if yes is there an easy way to insert these data in G4NDL? Thanks in advance Jean-Etienne Sauvestre

i would like to know why my question has a prority qualified as trivial. Is it so trivial?
You set the priority (P5) and severity (trivial) yourself (click on the "1 vote" link). Those are the default values when you create a new bug report. You may change them by following the "(vote)" link.
Hi Jean-Etienne As I reported you before, this problem is already fixed. Tatsumi
hi tatsumi, thanks a lot for having fixed this problem jean-etienne
Hi The fix is avialble in Geant4 v9.4.beta. V9.3.p01 also included some fixes about this. Tatsumi
