Dear Experts
I wanted to model Am-241 Alpha counts into a detector. The input file is
attached.
I always get the same error and I would like to understand what's happening.
The error message is:
Predictions for residual nuclei production and ***
*** decays require the activation of heavy fragment ***
*** evaporation by means of the PHYSICS/EVAPORAT card ***
*** look at the manual and release notes for further ***
*** details ***
*** Execution terminated ***
I added the PHYSICS/EVAPORAT card but it gives still the same error.
Maybe the experts can look at my file ?
I must admit I have never calculated alpha counts before
Thank you so much !
