<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt"><SPAN lang=EN-US style="FONT-SIZE: 12pt"><FONT face="Times New Roman">I want to calculate the neutron static structure factor based on the results of vibrational frequencies and eigenmodes obtained by the line-response method. The paper (Phys. Rev. B 2000, 61:3951-3959, Vibrational amplitudes in vitreous silica) and Paolo Umari's thesis gave the calculated formula. I tried to code it, but the results are wrong. I was wondering if there is a code in QE to calculate it. Can anyone who <SPAN style="mso-bidi-font-style: italic">successfully calculated </SPAN>the neutron static structure factor give me some help?<o:p></o:p></FONT></SPAN></DIV>
