The questions from textbook #6(2) using the pauli matrices, prove equation (10-6) on page 159. 10-1 eigenstates of spin 1/2 159 where (10-5) are the pauli matrices. they satisfy the commutation relations (10-6) and so on, as they must, to satisfy (10-1), and they also satisfy (10-7) the pauli matrices also anticommute: (10-8) these relations are peculiar to the spin 1/2 representations and do not hold for the -i matrices, for example. the eigenstates of s, will be represented by a two-component columa vector, which we call spinor. to find these eigenspinors, we solve (10-9) that is, using (10-4)
