)) describes the precession motion of an electron within a magnetic field aligned along the +z-axis. At t=0, the spin of the electron is in the positive x-direction. For t>0, calculate the probability for measuring the angular momentum of the particle to be (a) ħ/2 along the z-direction, and (b) ħ/2 along the x-direction. 4 The quantum mechanical state|4(t))= -iot/2 e iot/2 + e
