The spin density matrix for particles of arbitrary intrinsic angular momentum is explicitly expressed in terms of directly measurable quantities. The latter are taken to be either expectation values of components of multipole moments, or the relative weights of partial beams split up by a Stern-Gerl
## Abstract A class of graphs ${\cal C}$ ordered by the homomorphism relation is __universal__ if every countable partial order can be embedded in ${\cal C}$. It is known (see [1,3]) that the class $\cal C\_{k}$ of __k__βcolorable graphs, for any fixed ${k}\geq 3 $, induces a universal partial orde
