For 10 points, name this German physicist who lends his name to a doubly eponymous approximation with Oppenheimer.
The internuclear and interelectronic repulsions in an ionic lattice are named after this man, and those forces, when paired with the Coulombic energy in terms of Madelung constants, can be used to find the lattice energy via an equation name for him and Landé. Interparticle distance is preserved in inertial frames of a moving object in his namesake rigidity, and this man interpreted (*) probability as the square of the wave function. With a student, he names the idea that nuclear motion can be neglected due to large relative nuclear mass in the Schrodinger equation.
