From: Doug [ddb@r3401.rlem.titech.ac.jp] Newsgroups: sci.techniques.xtallography Subject: atomic scattering factors Date: 06 Dec 2001 01:30:25 Hello, according to Int. Tab Vol C. P476 the Cromer-Mann coefficients generally used to approximate atomic scattering factors in xtallography are derived from the non-relativisitic Hartree-Fock calculations of Cromer and Mann (1968) and the relativistic H-F calculations of Cromer and Waber (1968) Because those results were so fundamental to crystallography, I was wondering if the original Hartree-Fock source code and relevent wavefunctions used therein were archived someplace and generally available? For curiosity value really. thanks Doug |
