Homework Help: Einstein coefficients

  1. Jul 2, 2012 #1
    1. The problem statement, all variables and given/known data
    Calculate the Einstein coefficient of spontaneous emission for nitrogen transitioning from Ei: 32P1/2 to Ek: 32S1/2. Total duration τ = 16ns, emission wavelength λ = 589.593 nm.

    2. Relevant equations
    3. The attempt at a solution
    I want to use

    [itex]A_{ik} = \frac{2}{3}\frac{e^{2}\omega^{3}_{ik}}{\epsilon_{0}c^{3}h}\cdot \left|\left\langle \psi_{i}| \hat{r} |\psi_{k}\right\rangle\right|^{2}[/itex]

    but I've never done calculations with the wave functions of multi-electron atoms - can I just use the wave functions for H seeing as [itex]\psi_{i},\psi_{k}[/itex] are really the wave functions of a single electron in two states?
