full_question: Along with orbitons and holons, quasiparticles carrying this property are formed from electrons in Luttinger liquids, which carry density waves in charge and this property. Similar wave-like disturbances in the collective structure of this property for a crystal lattice are quantized into magnons. This property separates orthohydrogen from parahydrogen, and its total value is 0 for singlet states and 1 for triplet states. This property causes a beam of silver atoms sent through an inhomogeneous magnetic field to split into two beams instead of forming a continuous band. This property, described by a set of Hermitian unitary matrices named for Wolfgang Pauli, was discovered in the Stern-Gerlach experiment. For 10 points, name this intrinsic form of angular momentum, whose quantum number can be plus or minus one-half for electrons.

raw_answer: spin angular momentum [prompt on "angular momentum" before mention]
