FWHM Parameters

The profile shape for T.O.F is a pseudo voigt function convoluted with special function.

 

Gaussian component:

The variance of the Gaussian component of the peak shape in TOF neutrons is given by:

 

                                  

 

where d is the d-spacing in angstroms, Sig2 in (microsecs/Å2)2, Sig1 in (microsecs/Å2) and Sig0 in (microsecs2)

 

Lorentzian component:

The FWHM of the Lorentzian component of the peak shape in TOF neutrons is given by:

 

                     

 

where d is the d-spacing in angstroms, Gam2 in (microsecs/Å2), Gam1 in (microsecs/Å) and Gam0 in microsecs.

Parameters defining the variation of the exponential decay function with d-spacing.
