The energies of the 3 lowest states of an atom are E = -14 eV, E, = -9 eV and E = -7 eV. The Einstein coefficients are A10 =3x10^8 , A20=1.2x10^8 s' and A21= 8x10^7 s. If a large number of atoms are in the energy level E2, the mean radiative lifetime of this excited state is = The energies of the 3 lowest states of an atom are E = -14 eV, E, = -9 eV and E = -7 eV.
