Dear Rachid Makhloufi ,

you are right; the term 'spectrum' is not applicable here. The term 'spectrum' relates to frequency, wavelengths and energy dependend plots/presentations.

In the case of x-ray diffraction one may also say "diffraction pattern". This holds for one dimensional as well as for two dimensional ones.

Best regards

G.M.

Dear Gerhard Martens,

I wish to thank you so much for your contribution.

best wishes.

I like to use "X-ray diffraction pattern"

Diffractogram is enough.

The output from an X-ray diffraction experiment is usually presented as a diffractogram in which the intensity of diffracted x-rays is shown as a function of the scanning angle 2θ. (c)
