5. Diagonalization of a spin-1 operator. For a spin-1 system, Hilbert space is spanned by three basis vectors. We work in S₂ representation. The eigenvalues of S₂ are +h, 0, and -ħ and the corresponding base kets are 11), 10), and -1). (a) Give S₂ in eigen representation in Dirac notation and the corresponding matrix representation. (b) Consider the observable given by A=-11X11 +11X0-10X(1| + e|-1)-1| where e is real. i. Verify that A is Hermitian. ii. Find the eigenvalues and enkets of A.
