52) At a given instant of time, a rigid rotator is in the state(adsbygoogle = window.adsbygoogle || []).push({});

psi(theta,phi) = (3/4)^.5 sin(theta)sin(phi), where theta is

the polar angle relative to the z-axis and phi is the azimuthal angle.

Measurement will find which of the following possible values of the z-component of the angular momentum, Lz?

(A) 0

(B) hbar/2, -hbar/2

(C) hbar, -hbar

(D) 2hbar, -2hbar

(E) hbar, 0, -hbar

the answer is C, and I wonder why in vain :grumpy:

Thank you all!
