Figure 1
A plot of the electron density using different descriptions at a distance r in atomic units from a hydrogen atom. The solid blue line represents the electron density according to the Gaussian functions of Maslen et al. (2006 ), the orange dotted line represents the electron density when employing a single Slater-type function with an exponent of 1.15 in agreement with the scattering factor of Stewart et al. (1965 ) and the green dashed line shows the electron density of a hydrogen atom in the unbound state using a Slater-type function. |
