The Hydrogen Atom 22.1 Radial Wavefunction
... As with the infinite square well, it makes sense to let κ = −2~m E (negative inside the square root, now – bound states will have E < 0 and we want to make κ real). We want to define a new “coordinate” ρ ≡ κ r. The advantage is to render the coordinate variable itself unitless. Whenever we want to c ...
