Eric,
I was thinking that the neutrons would move relatively freely through matter since they lack a charge to interact and the physical sizes of the nuclei as well as the neutron are so small compared to the electron orbitals. How quickly does the cross section fall as neutron energy goes up? Can you relate them as an inverse proportion? If the neutrons become extremely cold do you see them being reflected by the electrons of the atom? Give this thought a little consideration. Being cold is just another way of saying that they are moving very slowly relative to the target atoms. It would seem that the motion of the target atoms themselves would tend to defeat the entire concept of ultra cold neutrons since their relative motion would be so much greater. Why would it not be necessary to keep both parts of the equation ultra cold if we are speaking of relative motion? The implication is that it would make very little difference in performance whether or not the generated neutrons were cold relative to our observation point.

Since the path is longer, their chances of being captured increases...but maybe this is already included in the concept of cross-section? That's kind of what I was thinking -- the more elastic collisions there are that don't result in an escape, the more there's a chance for a capture. But I was hoping you would know this one. The cross sections are a little bit magical. Eric
