SMA #8: Bohr and Schrödinger Models of Hydrogen Here we investigate the relationship between the Schrödinger and Bohr models of hydrogen-like atoms, following our work in class on both 9 1. Using the appropriate Schrödinger wavefunctions, compute the most probable electron-proton radii (i.e., distances) for 1s, 2p, and 3d states. Do these agree with the corresponding Bohr radii? Hint #1: Remember to maximize the "radial distribution function" P(r) = [rR(r)], i.e., to include the radial Jacobian factor (r2) in your...
