scattering - What is the physical interpretation of imaginary terms in the neutron optical potential model?


I'm doing a computational project on neutron scattering and I've found that if you simulate (n,n) collisions on Uranium 238, the program predicts resonances not found in experimental data.


The optical model includes imaginary surface or volume potential terms which supposedly damp out these resonances.


How should an imaginary potential be interpreted in this context?
