The radial part of the Schrödinger equation for a system of two particles, of charges +e and -e, interacting through a Coulombic potential is: \frac{-\hbar^2}{2\mu r^2} \frac{d}{dr} \left( r^2 \frac{dR(r)}{dr} \right) - \frac{e^2 R(r)}{4\pi \epsilon_0 r} + \frac{\hbar^2}{2\mu r^2} l(l+1) R(r) = E R(r). (a) Show that the function: $R(r) = \frac{1}{4\sqrt{2\pi}} \left( \frac{1}{a_0} \right)^{3/2} \left( 2 - \frac{r}{a_0} \right) \exp\left( -\frac{r}{2a_0} \right)$, with $l = 0$, is a solution of the radial Schrödinger equation with the energy eigenvalue $E = \frac{-\mu e^4}{8\hbar^2 (4\pi \epsilon_0)^2}$. Take $a_0 = \frac{\hbar^2 (4\pi \epsilon_0)}{\mu e^2}$.

Q8. Gaussian functions are easier to integrate numerically than exponential decays. For this reason, basis sets of Gaussian functions are frequently used for variational calculations. [4] Using the Gaussian trial wave function $\phi(r) = \exp(-cr^2)$ for the hydrogen atom gives $E' = \frac{3h^2}{8\pi^2\mu}c - \frac{e^2}{\sqrt{2\pi^{3/2}\epsilon_0}}\sqrt{c}$ a) Calculate the optimal values of c and the variational energy. b) Compare the variational energy to the exact energy $\mu e^4/8\epsilon_0^2h^2$ for the ground-state hydrogen atom.
