Question on usage of 'Which'

"Other forms of elastic X-ray scattering include powder diffraction, SAXS and several types of X-ray fiber diffraction, which was used by Rosalind Franklin in determining the double-helix structure of DNA."

As stated above , may i know what is the 'which' refered to , is it all the forms of elastic X- ray scattering, all just the several types of X-ray fiber diffraction ?

Since the verb is 'was', 'which' must refer only to X-ray fiber diffraction -- and presumably only one of the types.
