[phenixbb] neutron scattering table for specific metal isotope

Hello, I would like to alter the neutron scattering table for phenix.refine so that it takes into account the correct bcoherent value for the metal isotope present in my structure. the difference is significative between the natural occurence bcoh... i have been looking around in chem_data but could not find the neutron scattering tables. does anyone have any idea where to look please? cheerios -- Dr. Maxime Cuypers
