The f Orbitals

The seven real hydrogenic 4f wavefunctions R43(r) Y3m(theta, phi), each drawn as the isosurface |psi| = 3.109079e-03. The surface radius is solved along 44 x 88 sample directions from the outer root of |R43(r)| = c / |Y|, at one isovalue and one scale of 6.8010 units per Bohr radius for all seven. Colour carries the sign of the wavefunction.
