Re: Input runs fine but all detectors/bins show zero tally.

Hi
You need to enable LAM-BIAS to get some neutrons in a photonuclear reaction.
Check the manual for an example.
Also, you have used LOW-MAT card for Titanium but have used Tantalum as
target material. Is that what you want to do?
In general, LOW-MAT and LOW-NEUT cards are not necessary unless you have
something different in mind.
Regards
Sunil
