Dear Forum :
I am learning how to score the cross section and yield of 18O(p,n) reaction.
I am confused interpreting the output from USRYIELD.
Part 1. The cross section
The proton beam energy is 0.015GeV( 15MeV).
The XS0-0.01, 61 bin scoring the neutron binning from 0 to 10MeV, the
results of cross section gives around 30mb/0.01GeV.
The XS0-1, 65 bin scoring the neutron binning from 0 to 1GeV, the results
of cross section gives 0.3mb/1GeV.
What is the cross section of 18O(p,n) at 15MeV, how to interpret it if I
want to compare it with the recommended cross section ?

Part 2. The yield
The Yd0-0.01, 63 bin scoring the neutron yield from 0 to 10MeV gives around
0.1 /0.01GeV.
The Yd0-1, 66 bin scoring the neutron binning from 0 to 1GeV gives
1E-03/1GeV.
How many neutron generated from 18O(p,n) per 15MeV proton.
I know most of the emitting neutron is below 10MeV,but it confuse me how to
interpret different binning.
Thanks in advance
Lee
