Dear Fluka experts:
I am trying to simulate a progress of a protron hit a target of lead-bismuth. The nuclear density of lead-bismuth is as follows:
lead 204 1.93423*10^20
lead 206 3.11908*10^21
lead 207 2.91802*10^21
lead 208 6.70371*10^21
bismuth 209 1.59861*10^22
It seems I did not succeed to define the lead-bismuth. Would you please tell me how to define it? Thank you very much!
Best wishes
