Changing the spin of an electron

  1. Jun 27, 2011 #1
    Is it possible to change the spin of an electron (or any particle) by supplying some energy to it?

    The spin itself as in changing the 1/2 to 2/2? If so, no. It is not possible. However it is possible to change the direction of the spin, as in changing it from an up spin to a down spin.

    By changing I mean +1/2 to -1/2

    I believe so, as the + and - simply refer to the direction.

    Isn't that what a magnetic field does? The initially randomly spinning electrons change their spins to align with the magnetic field.

    in order to flip a spin you don't necessarily have to supply energy but angular momentum ...
