- When I went to the UCLA lab a few months ago, Prof Putterman said that
- the light appeared to have a overall macroscopic polarization pattern,
- which you would not expect from independent atomic recombinations, but
- rather pointing towards some overall collective phenomenon.

- I don't know what more recent experimental results say.
