of: a system
in: quantum mechanics (or, more generally, quantum physics)
is: the most complete description of the properties of a system allowed by its wavefunction. It may include the values that various observables (such as momentum and energy) will be found to have if measured, or it may be confined to statements about the relative probability of various possible outcomes of a measurement. [M6.4, P7.1, P8.3, P8.4, P10.3, P10.4]
is specified: in sufficiently simple cases, by the values of a set of quantum numbers. [M6.4, P7.1, P8.3, P8.4, P10.4]
See stationary state.
