    "abstract": "Consider a spin s prepared in a pure state. It is shown that, generically,\nthe moduli of the (2s+1) spin components along three directions in space\ndetermine the state unambiguously. These probabilities are accessible\nexperimentally by means of a standard Stern-Gerlach apparatus. To reconstruct a\npure spin state is therefore possible on the basis of 3(2s+1) measured\nintensities.",
