How to calculate/get info about inelastic scattered neutron?

AI Thread Summary
The discussion focuses on calculating the energy loss of neutrons during inelastic scattering, particularly when colliding with light nuclei like 19F, 16O, or 9Be at MeV levels. The user initially struggled to find resources but later discovered that the first excited state of the nucleus is crucial for determining the Q-value, which helps calculate the energy threshold for inelastic scattering. They found a useful resource that outlines the necessary calculations and the importance of knowing the excitation states of the nuclides involved. The user concludes that the process seems straightforward once the relevant parameters are understood. Overall, the thread highlights the significance of excitation states in neutron scattering calculations.

I have been researching in the Forum, but I did not see anything conclusive about this: sorry if that was posted anywhere else here, I am new here :smile:.

The energy loss of a neutron after an elastic scattering is a pretty straightforward calculation that can be done by hand. However, I am straggling to get information about how to calculate the same for an inelastic scattering, or an online database where I can find such information.

I would be interested to know which is the resulting energy of a neutron which scatters light nucleai like 19F, 16O or 9Be at MeV level. For instance, 14MeV neutron colliding to 19F: 19F(n,n'), which is the final energy of the collided neutron n'?

Thanks in advance!

Update:

Ok, I think I got it. I found this interesting resource: http://web.utk.edu/~rpevey/NE406/lesson8.htm

It looks like important is to know the first excited state of the nuclei after the scattering with an incident neutron with an energy E. This 1st excited state gives the Q-value, which is used to calculate the energy threshold of the inelastic scatter interaction:

Knowing Et and E the ratio Δ between them is calculated as:

And then an energy interval for the inelastically scattered neutron can be calculated:

The excitation states of the nuclides can be found here: http://www.nndc.bnl.gov/chart/

So if I did not understand something wrong this looks also pretty straightforward :smile:
 
Hello everyone, I am currently working on a burnup calculation for a fuel assembly with repeated geometric structures using MCNP6. I have defined two materials (Material 1 and Material 2) which are actually the same material but located in different positions. However, after running the calculation with the BURN card, I am encountering an issue where all burnup information(power fraction(Initial input is 1,but output file is 0), burnup, mass, etc.) for Material 2 is zero, while Material 1...
Hi everyone, I'm a complete beginner with MCNP and trying to learn how to perform burnup calculations. Right now, I'm feeling a bit lost and not sure where to start. I found the OECD-NEA Burnup Credit Calculational Criticality Benchmark (Phase I-B) and was wondering if anyone has worked through this specific benchmark using MCNP6? If so, would you be willing to share your MCNP input file for it? Seeing an actual working example would be incredibly helpful for my learning. I'd be really...
