Dear Rex,
These issues of energy overlaps are addressed in theory, for either diffraction
probe, in Cruickshank, Helliwell and Moffat 1987 Acta Cryst, and also by the
same authors in 1991 Acta Cryst for spatial overlaps, and in practice in eg
Ren et al JSR 1999 and Nieh et al JSR 1999.

Maybe we should be using neutrinos, in hopes of getting some data
_literally_ before there is any damage.

That value, 2200m/s, is pretty slow--there are some bullets that go
faster than that, I think...

Re Neutron Data Collection:
1. What are the limits to data set completeness imposed by a Laue experiment
versus those of monochromatic data collection?
2. What problems are caused by flash freezing the larger protein crystals used
for neutron data collection which do not occur for X-ray data
this helps.

Hello Dr. Palmer-
There may be other representatives in the literature by now but the one
study I know of that examines the usefulness and limitations of determining
cryo-neutron structures is The 15-K neutron structure of saccharide-free

Dear Rex,

versus those of monochromatic data collection?
Laue allows for a greater number of Bragg reflections to be measured compared
to monochromatic data collection over a give time period. The limiting factor
