A hydrogen atom is in a d state. In the absence of an external magnetic field, the states with different ml values have (approximately) the same energy. Consider the interaction of the magnetic field with the atom’s orbital magnetic dipole moment. (a) Calculate the splitting (in electron volts) of the ml levels when the atom is put in a 0.800 T magnetic field that is in the +z@direction. (b) Which ml level will have the lowest energy? (c) Draw an energy-level diagram that shows the d levels with and without the external magnetic field.
