Unformatted text preview: v v v C ( r, θ ) e i mφ v v v 2 = | C ( r, θ ) | 2 , is independent of φ . So to be in a state of deFnite angular momentum, the particle must be at all sides of the axis with equal probability. A macroscopic particle will at any given time be at a single angle compared to the axis, not at all angles at once. So, a macroscopic particle will have indeterminacy in angular momentum, just like it has indeterminacy in position, linear momentum, energy, etcetera. Since the probability distribution of an eigenstate is independent of φ , it is called “axisym-metric around the z-axis”. Note that the wave function itself is only axisymmetric if m = 0, in other words, if the angular momentum in the z-direction is zero. Eigenstates with di±erent angular momentum look the same if you just look at the probability distribution. 4.1.3 Square angular momentum...
