Thanks very much to those that replied. That cross polarisation experiment with photons was the sort of thing I was looking for. In response to some of the other omments, my question was much more subtle than I originally let on. I have no doubt that detection of which slit the particle went...

I'm terribly sorry, I've been totally unclear! The result I'm calling into question is the breakdown of the interference pattern once the electrons are being detected as going through one slit or the other. Feynman's thought experiment suggests a light source hidden behind the metal plate...

Here's my puzzle... Electrons through a single slit one at time - standard distribution Electrons through a double slit one at a time - interference pattern Set up a detector to observe which slit the electrons passed through - back to a standard distribution. This is all well and good...
