it's been done. they oscillate http://www.ph.utexas.edu/propagator/view.php?issue=200905&section=res&number=1 " Somewhere between Illinois and Minnesota, the federal government lost some neutrinos. No matter...." -Foxnews http://www.foxnews.com/story/0,2933,190084,00.html Yep! It has been done, which is why it was a trick question. The hardest part of the experiment IMHO is the difficulty is making a slit. The neutrinos pass effortlessly through solid matter so making a slit is difficult, at best. Just looking for wave behavior is difficult. The detector has already found evidence of exploding stars and helped separate the different types of neutrinos. Fun things are happening in the world of physics. Well I had heard of the massive underground neutrino detectors, that use light sensitive photo cells to detect the minute light emitted when a neutrino had a direct hit with an atomic nucleus, however could not imagine what we could use for a slit, or a rig to detect in any sense the sum total of neutrino's emitted from what, a collider, or the sun? Never stop being amazed. BTW what did they use as a slit, and I wonder what their detector rig looks like hmm.

The wave interference was the conversion of neutrino types. I would have a hard time buying this one except it is apparently predictable and reproducible. Go figger! Here is a picture of the one at Los Alamos. It is a different type.

hmm interesting, yes that picture is what I had as a mental image. I could not figure out how that as a detector could be used in an actual experiment where we could determine where neutrino's from a given source could travel through slits they may just penetrate anyways and then measure interference from, but hey two years of undergraduate physics makes not a experimental physicist.
