The muonium atom is a hydrogen atom with the electron replaced by a μ – particle. The μ – is identical to an electron but has a mass 207 times as great as the electron.

(a) Calculate the energies of the five lowest energy levels of muonium using the reduced mass as given by Equation 37-47 in Problem 17.

(b) Do transitions between any of the levels found in (a) fall in the visible range of wavelengths, i.e., between λ = 700 nm and 400 nm? If so, which transitions are these?
