In a stationary state
WebFeb 15, 2024 · Stationary states: these are states represented by wavefunctions whose probability density function , that is, the pdf is only a function of space and does not vary in time at different points in space. Bound states: these are states described by wavefunctions that are nonzero only within a certain region of space and zero everywhere else. WebIf the system is in one of the stationary states, then you can perform a huge number of experiments on the system to measure the energy of the system, you will always get the same measurement, i.e. the eigen value of the corresponding stationary state …

A stationary state is a quantum state with all observables independent of time. It is an eigenvector of the energy operator (instead of a quantum superposition of different energies). It is also called energy eigenvector, energy eigenstate, energy eigenfunction, or energy eigenket.
