How do Cesium gas atoms demagnetise

  1. Nov 3, 2011 #1
    Hello guys :),

    if we magnetise Cs atoms with a magnetic field (or basically any other method like pumping), and got all the spins (moments) aligned in 1 direction, and then turn the cause of the alignment off, how will the decay profile look like? is it gonna be a clean exponential decay? what are the equations governing this behavior?

    I don't really know where to start with the answer to this.

    I would appreciate an answer, reference, essay, article, book, or whatever kind of help you may provide me :-)

    Thank you for any efforts :-)

    You should probably try to find a book about NMR.
    In the "classical" equations for this you end up with two time constants (T1 and T2) which govern the relaxation and the dephasing.

    Thank you for your reply.

    Could you please mention some specific book?
