Calulating intensities

[stuart]

Hi

I was trying to compare the intensities given from a simulation when
using different energy/wavelength neutrons, and have been trying to
understand the way in which the monochromator mosaicity would affect the
number reflected, for those different incident energies/wavelengths.

Should the energy spread of the neutrons, from the source be different
for each energy simulated in order to give an identical wavelength
spread, incident upon the monochromator?  Or maybe I'm thinking about it
the wrong way!
