Compare the obtained result with the value given the williams tables
1. a) Using the Slater model, determine the energy needed to produce a K-shell vacancy in copper. Compare the obtained result with the value given in the Williams Tables. Why is the result obtained from the Slater approach bigger than the experimental value reported by Williams?
b) Determine then the energy needed to produce a hollow copper atom, i.e., a copper atom with two K-shell vacancies. What can you conclude from a comparison of the results obtained in a) and b)?
5. a) What are the values of the quantum numbers S, L and J in the ground state of nitrogen ?
b) What are the angles between the total angular momentum
