Exercise 16.1.5.* Solve the variational problem for the 1-1 states of the electron in a potential Ve/r. In your trial function incorporate (i) correct behavior as r0, appropri- ate to =1, (ii) correct number of nodes to minimize energy, (iii) correct behavior of wave function as rco in a Coulomb potential (i.e., exponential instead of Gaussian damping). Does it matter what m you choose for Y? Comment on the relation of the energy bound you obtain to the exact answer.
