Low-energy neutron capture

Thank you so much for your response.
I have another question regarding the low-energy neutron capture. I have added LOW pwxs card in my input and now I am able to find neutrons that have been produced with jtrack=8 ( after interaction of neutron with lead). Now I have activated usdraw in my mgdraw file and I am going to specifically determine neutron that has created a multiplicity (several neutrons per one interaction of neutron with lead) I am wondering which parameter should I add to my file to specify that neutron. I have attached my mg draw and input file below.
Thanks in advance

Dear Razieh,

I will look into it as soon as possible.

Cheers,

Dear Razieh,

I would recommend you to use LTRACK and ATRACK, which give you the information about the generation number and the age of the projectile neutron, respectively. Its reaction products can be found in the secondary stack (genstk.inc), where neutrons are identified by KPART(I)=8 with I=1,NP.

More general information about what a stack is, you can find in this post. More detailed use of the stacks is explained here.

Please let us know if you have any other questions.

Cheers,
Barbara
