Consider a large ensemble of electrons, all in the same quantum state. When the
expectation value of Sy is measured the value of ¯h/2 is obtained. When the expectation value
of Sz is measured the obtained value is 0.
(a) Determine the state of the electrons and express it as a superposition of states with the
positive and negative projections of spin on the z-axis.
(b) If the expectation value of Sx is measured, what value will be obtained
Problem 2. Consider a large ensemble of electrons, all in the same quantum state. When the expectation value of S, is measured the value of h/2 is obtained. When the expectation value of S. is measured the obtained value is 0. (a) Determine the state of the electrons and express it as a superposition of states with the positive and negative projections of spin on the z-axis. (b) If the expectation value of S, is measured, what value will be obtained?
