During the transition P -> S from the excited state of the atom to the ground state, a doublet l1 = 455.1 nm and l2 = 458.9 nm is emitted. What lines corresponding to the transition 3S1/2 -> 2P3/2 will be observed in the absorption spectrum of a gas consisting of such atoms when a magnetic field B = 50 kG is applied at a temperature T = 0.5 K?
