From: Tightly binding valence electron in aluminum observed through X-ray charge density study
Charge-density difference between experiment and theory. The drawing plane is indicating in the left inset inside black dotted line. Aluminum atom is at the center of the plane. The contour interval is 0.005 eÅ−3 in −0.05–0.05 eÅ−3 region. Solid and dotted lines show positive and negative contours, respectively.
