Hi everyone,
Does anyone remember offhand how to turn on the output that includes
calculated particle size when refining with a symmetry specific size
model in Fullprof? I haven't looked at the program in a few years and
am afraid I can't quite remember...

Hi Xiujun,
Jon is correct, but to answer your question fully, the angle is used in an
equation to scale the peaks as function of 2theta.
If you look in the Technical Reference Manual of TOPAS states that the LP
factor (for x-rays) is given by
LP = (1 + cos(2th)^2 cos(2th_m)^2) / (cos(theta)
Dear Peter,
Of course the LP correction can't be sample-dependent and for your
configuration LP=0 should be Ok for all samples. It seems that you have an
intensity loss at high-angles that may be partly compensated by LP=90. Possible
reason may be in a misalignment of the anti-scattering
Dear All,
In this scenario, which should be the number for LP in Topas if ones has a
D8 with a primary monochromator for pure CuKalpha1?
thanks for the response,
