4. What is the ground-state energy of positronium, the bound state of an electron and positron? Hint: electron and positron have equal masses, so one cannot assume that one of the particles is at rest, while the other orbits around it. It is necessary to calculate using the reduced mass

Positronium is a hydrogen-like atom that consists of a positron (anti-electron) and an electron revolving around one another. The positron has the same mass as an electron but the opposite charge (same magnitude, but positive). a. Use Bohr's theory and the reduced mass (see problem lb and Krane Sec. 6.8) of the positron-electron system to show that 6.8 eV En= --"2_ , for positronium. b. The n -1 to n-2 transition in positronium has been measured to be roughly 1.2336...
