Presentation on theme: "Is the natural linewidth a homogeneous or inhomogenous broadening"— Presentation transcript:

1 Is the natural linewidth a homogeneous or inhomogenous broadening
mechanism? homogeneous inhomogeneous depends on actual time scale of decay

2 Is the natural linewidth a homogeneous or inhomogenous broadening
mechanism? homogeneous inhomogeneous depends on actual time scale of decay

3 Is pressure broadening a homogeneous or inhomogenous broadening
mechanism? homogeneous inhomogeneous depends on actual time scale of decay

4 Is pressure broadening a homogeneous or inhomogenous broadening
mechanism? homogeneous inhomogeneous depends on actual time scale of decay Note that most textbooks characterize pressure broadening as homogeneous. However, this is not true in general and depends on whether the time between collisions is e.g. short compared to the natural lifetime.

5 Is Doppler broadening a homogeneous or inhomogenous broadening
mechanism? homogeneous inhomogeneous depends on actual time scale of decay

6 Is Doppler broadening a homogeneous or inhomogenous broadening
mechanism? homogeneous inhomogeneous depends on actual time scale of decay
