"few nanoseconds or less"
First, the timing depends on the energy gap value. Second, it is generally not correct to suggest a picture like
- the "↑" state before T0
- transition started at T0
- intermediate state between T0 and T1
- transition ended at T1
- the "↓" state after T1.
In the Schrödinger picture, we will always see some superposed state with the ↑ amplitude gradually decreasing and ↓ amplitude increasing. More general, the moment of a transition is always uncertain, and speculation such as "transition started at… and ended at…" do not have a sense. Incnis Mrsi (talk) 20:03, 22 September 2012 (UTC)
