The positron is a particle identical to the electron except that it carries a positive charge of e. Positronium is the bound state of an electron and positron.

(a) Calculate the energies of the five lowest energy states of positronium 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? If so, which transitions arethese?
