  3. Resonances in scattering from potentials - Wikipedia

    en.wikipedia.org/wiki/Resonances_in_scattering...

    In quantum mechanics, resonance cross section occurs in the context of quantum scattering theory, which deals with studying the scattering of quantum particles from potentials. The scattering problem deals with the calculation of flux distribution of scattered particles/waves as a function of the potential, and of the state (characterized by ...

  4. Partial-wave analysis - Wikipedia

    en.wikipedia.org/wiki/Partial-wave_analysis

    Partial-wave analysis, in the context of quantum mechanics, refers to a technique for solving scattering problems by decomposing each wave into its constituent angular-momentum components and solving using boundary conditions.

  5. Step potential - Wikipedia

    en.wikipedia.org/wiki/Step_potential

    In quantum mechanics and scattering theory, the one-dimensional step potential is an idealized system used to model incident, reflected and transmitted matter waves.The problem consists of solving the time-independent Schrödinger equation for a particle with a step-like potential in one dimension.

    The quantum inverse scattering method relates two different approaches: the Bethe ansatz, a method of solving integrable quantum models in one space and one time dimension. [citation needed] the inverse scattering transform, a method of solving classical integrable differential equations of the evolutionary type. [citation needed]

  7. Lippmann–Schwinger equation - Wikipedia

    en.wikipedia.org/wiki/Lippmann–Schwinger_equation

    The Lippmann–Schwinger equation (named after Bernard Lippmann and Julian Schwinger [1]) is one of the most used equations to describe particle collisions – or, more precisely, scattering – in quantum mechanics. It may be used in scattering of molecules, atoms, neutrons, photons or any other particles and is important mainly in atomic ...

  8. S-matrix - Wikipedia

    en.wikipedia.org/wiki/S-matrix

    In physics, the S-matrix or scattering matrix is a matrix that relates the initial state and the final state of a physical system undergoing a scattering process.It is used in quantum mechanics, scattering theory and quantum field theory (QFT).

  9. Rectangular potential barrier - Wikipedia

    en.wikipedia.org/wiki/Rectangular_potential_barrier

    In quantum mechanics, the rectangular (or, at times, square) potential barrier is a standard one-dimensional problem that demonstrates the phenomena of wave-mechanical tunneling (also called "quantum tunneling") and wave-mechanical reflection.
