Dear Mikhail,
Thanks for your help. I am sorry to disturb you again. I don't know why I always failed to send my last email to the fluka-discuss, maybe it's caused by the size of attachments. The problem is listed on this web link:
http://www.fluka.org/web_archive/earchive/new-fluka-discuss/12843.html
I run it by changing the boron definition as you give, and it works. In the problem of neutron activation,I think it is a puzzled task to define every element by this step (explicitly define the natural element consist of several isotopes) since there are many elements involving in the activation process. I want to know whether this method or step is necessary for other elements or not(e.g., Li-6, Cu-64, Fe-56 ...)?
best regards!
Yang
