consider a particle of mass m confined to move within the z = 0 plane. suppose the particle is in a state with wave function 2v3 (11.46) a measurement of the angular momentum of the particle with respect to the origin is carried out. what are the possible values, and their probabilities? what is the expectation value (ie the average over many measurements, ifthe system has been prepared in the above state before each measurement takes place)? 0the letter comes from the hebrew alphabet and is called "aleph". physicists resort to from the latin and greek alphabets. when we've run out of letters
