Stern-Gerlach deflection experiment

From our present standpoint, we know that the deflection of a silver atom in the Stern-Gerlach experiment is caused by the interaction of its electronic spin angular momentum S with an inhomogeneous magnetic field. The projection of S on the direction of this field, Ms, is quantized. For a silver atom, Ms can take two values +vjh and — h, where h is Planck s constant h over 2ji and adopts a value of 1.054571596 x 10-34 Js in cgi units. 

We focused on the size-selected cluster ions with small sizes in the above. On the other hand, the magnetic moments of neutral transition metal clusters in the size range between several and several hundreds are successfully measured by deflection in an inhomogeneous magnetic field. This method is basically the same as the Stern-Gerlach experiment known by the discovery of the electron spin by using the deflection of an atomic beam of silver.
