## Homework Statement

An observable is represented by the matrix

0 [itex]\frac{1}{\sqrt{2}}[/itex] 0

[itex]\frac{1}{\sqrt{2}}[/itex] 0 [itex]\frac{1}{\sqrt{2}}[/itex]

0 [itex]\frac{1}{\sqrt{2}}[/itex] 0

Find the normalized eigenvectors and corresponding eigenvalues.

## The Attempt at a Solution

I found the eigenvalues to be 0, -1, and 1

and the eigenvectors to be (1,0,-1), (1,-[itex]\sqrt{2}[/itex],1), and ((1,[itex]\sqrt{2}[/itex],1) (respectively)

I'm pretty sure these are right.

My problem comes with the word "normalized". The only place my lecture notes and book mention normalized eigenvectors is after the matrix is diagonalized, which seems unnecessary.
