Little wording confusion

  1. Sep 12, 2010 #1
    1. The problem statement, all variables and given/known data

    If I am told a spin (1/2) particle is originally in the state of a particular Hamiltonian (proportional to S(z)), does that imply the general state or spin-up? Because I am asked to find the probability that it will change its spin, which I can only make sense of assuming its talking about a specific spinor (in this case up).



    2. Relevant equations

    ...



    3. The attempt at a solution

    ...

    Yes, the poster deleted his own post. Possibly because he realized that he did too much work on solving this schoolwork question. Perhaps he will come back and post more of a hint or a leading question...

    Straightened it out. Am I supposed to get an energy transition value of h-bar, from spin-up to spin-down state? I imagine so since the eigenvalue of angular momentum is increased/decreased by h-bar. Right?
