Experimental Compton profiles of Be, Al and Ti and comparisons to generalized gradient approximation calculations
Experimental analysis of isotropic Compton profiles for beryllium, aluminum and titanium was performed to assess the radial core wavefunctions and pseudo-orbitals for valence electrons generated using a generalized gradient approximation based on norm-conserving pseudo-potential calculations.
