The positronium is an atomic system made by an e - and an e + bound by

Question:

The positronium is an atomic system made by an e^-and an e⁺ bound by the electromagnetic force.

(1) Determine the relationship that this condition imposes between the orbital momentum l, the total spin s and the charge conjugation C.

(2) Determine the relationship between l, s and n which allows the reaction e^-e⁺→ nγ to occur without violating C.

(3) What is the minimum number of photons in which the ortho-positronium (³S₁) and the para-positronium (¹S₀) can annihilate, respectively?
