Question

there is no spontaneous absorption why​

Answer 1

Answer:

Scenario 1 is similar to spontaneous emission where an atom interacts with the photon vacuum state, dumps a photon to the photon field and moves to an available lower exited state. ... As there is no such available energy level as the Photon field is already at its ground state, spontaneous absorption doesn't happen.
