Thanks a lot, I also thought there should be some relationship for it! That makes sense. So, let's say I'm able to find an eigenvalue, how do I move from here to probabilities? Do you have any clue? It's easy to find the expectation value, but not separate probability values.

So should I take each of the three terms separately and see if they are eigenfunctions? Then only two of them are. So, let's say if one term isn't an eigenfunction of an angular operator, does that mean that it doesn't have an angular momentum and I'm only considering two of the other functions...

I got 1/√π (½ ei(φ - Et/ħ) - ½ e-iEt/ħcos(2φ) + ½ ei(5φ - Et/ħ))

I don't quite grasp what you mean. Why don't they relate to the wave function? If we use this relationship of Lf = λf, I basically plugged in f as a wave function given and I can see that no λ fits here. Sorry for such dumb questions, it's just that I don't get a useful clue where to start and...

I also thought about the expectation value, but you're right, this has nothing to do with the probabilities, just the average angular momentum value. Right, so what I did was applying L operator to the wave function which gave me (with the dependence on time term): -ħ/√π (-½ ei(φ-Et/ħ) - ½...

Not sure how to write the functions via this forum properly, so I just uploaded the image to another host. http://i64.tinypic.com/dg12wz.jpg Does that work? Sorry for the inconvenience.

Homework Statement Basically, I'm dealing with part d) in this document: https://s3.amazonaws.com/iedu-attachments-message/b663095a5021cb6aee55657de728a8d7_bfbe0ba9d2f10f8ac9ef9d049934c1da.jpg. I have found that the angular momentum only depends on spatial coordinate and it doesn't on time. Is...

Is there a way you could show me the solution? It's quite hard for me to understand, although I believed I got it right. I'm trying to look at the free body diagram and I'm lost. This problem is due soon and I just can't figure it out.

So, I have to determine that angle using trigonometry for the lengths given, right? I could find that angle using tan here. Now, what about equilibrium problem? I need to find the opposite torque that has the same magnitude, but the opposite direction?
