Question:

a. Use the Clementi-Corongiu formula to estimate the correlation energy in the ground-state He atom and compare the result with the true value.
b. Use the Clementi-Corongiu formula to estimate the correlation energy in the ground-state N atom. Find the ground-state energy of the N atom by using data in the online reference in Sec. 10.5 to add up all the ionization energies of N. About what percentage of the true energy is the correlation energy in N?
