The problem still exists in ref-09

In the attached plots :
Top : Auger cascade triggered by an electronic capture (with rdecay01). Blue : ignoreCut = true.  Red : ignoreCut = false
Bottom : same cascade triggered by a photoelectric interaction (with TestEm14).
              As you can see, there is no anomaly is this case.

Hi Michel,

can you, please, send macro for rdecay01 and for TestEm14 which needs to be tested for this problem. To say truth, I do not yet understand the problem and which plots are correct.

Cheers,
Vladimir

there is macro atomicDeexcitation.mac in both examples.

the problem can be seen in plot 2 :

 1- electrons in range 1 keV -> 2 keV are fictious. They do not exist in other plots
 2- it must not have electrons below 100 eV : cut.  Compare with plot 4

 I believe that, if a user ask explicitly for atomic deexcitation, he wish to see them ...
 So, ignoreCut would be the default.

Hello Michel,

I have reproduce the problem. It is not a simple bug in configuration but likely problem inside atomic de-excitation module. I cannot find the reason and fix it for 11.1, all what I did is MR !3294, which a bit improve the example but do not resolve the issue. Some excuse to postpone this issue: it is some special regime, normally for radioactive decay ignoreCut should be true.
