Its an old experiment. Stern and Gerlich.

Consider the following and show me where I'm wrong. :) Draw an ellipse on a piece of paper. Cut it out. Stick a pin through one of the foci. The ellipse as a whole can be rotated about the pin. This is "l" (quantum number). The movement of the electron around the circumference of the ellipse is "s". No closed orbit -> no "s". If someone can find a reference to paper that shows the spin of free electrons (i.e. not attached to atoms), I'd love to see it. :) Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
