    Hi there,

    I have some questions which I cannot solve from my Quantum book. I would appretiate some hints as to how they should be solved. Thanks.

    Hi coffeem! :smile:
    well, that means you have to prove that (uab-uba)(uab-uba)* = 2 :wink:

    Thanks for your help, I really do appreciate it. I can expand the brackets and get:

    UabUab + UbaUba = 2 (since UabUba = 0)

    So would a reasonable answer be:

    Since (Uab-Uba)^2 is 2, to normalise this to 1, we must divide the eigenfunction by the square root of this?

    Thanks.

    Yes, except I'd say "we must divide it by the square root" …

    any multiple of (Uab-Uba) is an eigenfunction. :wink:
