Calculate PKA Velocity in 10keV Fe Collision

Click For Summary
SUMMARY

The discussion focuses on calculating the Primary Knock-On Atom (PKA) velocity resulting from a 10 keV collision in iron (Fe). The calculated PKA velocity is 2620.579 angstroms per picosecond (262057.9 m/s). The conversation highlights the assumption of an Fe-Fe collision and questions the incident particle, speculating it could be a neutron or an iron particle. The participants seek clarification on the energy transfer dynamics involved in this simulation.

PREREQUISITES
  • Understanding of collision cascade simulations

Hi,
I've been trying to understand a simulation for a collision cascade. The PhD that produced this code says that he is modelling a 10keV collision in Fe. From this he says that his PKA velocity is 2620.579 ang/ps or 262057.9 m/s and I'm wondering how did he get this?
I've assumed that the collision would transfer a maximum energy and I've assumed that it is an Fe-Fe collision since I don't know any other way of getting close to his value if I tried a Fe-n collision. So if anyone could help me figure this out please that would be really useful.

10 keV and 262km/s lead to A=28, something like silicon. Iron at that energy would be slower.

What is your primary particle that collides with the material?

It doesn't say what incident particle it is although I would assume a neutron. Although it could be an iron particle.
