Are different isotopes of the same element share the same neutron cross section data in FLAIR?

Dear all,

I want to simulate the following reaction;

n + Gd -> Gd(*) ...(1)
Gd(*)-> Gd +garma ...(2)

If I assign different mass number to Gd in reaction (1),that is to say
isotopes of Gd,there will be isotopes of Gd(*) coming out,which leads to
different energy distributions of garma in reaction(2).

And when I assign different mass number to Gd and I use USRTRACK card to
see the energy distribution of garma, the values of garma energy peak are
exactly the same.So I wonder if Gd with mass number 155 and 157,for
example,share the same neutron cross section,in the circumstance of a
constant neutron energy.

Yours,
Danny
