**of a particle, because [L**

*L*_{x}, L

_{y}] = i[itex]\hbar[/itex]L

_{z}which is not 0.

But what happens when L

_{z}does equal 0? Would we in principle be able to measure both the x and y components of the angular momentum with no uncertainty? What kind of state would this describe?

I've searched my textbooks and the web for an answer to this question, but I haven't found any, so maybe this is actually something really obvious which I'm not seeing! Thanks for your help!
