The latter is described by the wavefunction:formula_1where formula_2 is the position vector; formula_3; formula_4 is the incoming plane wave with the wavenumber formula_5 along the formula_6 axis; formula_7 is the outgoing spherical wave; formula_8 is the scattering angle; and formula_9 is the scattering amplitude.
:formula_1где formula_2 — координатный вектор; formula_3; formula_4 — входящая плоская волна с волновым вектором formula_5 вдоль оси formula_6; formula_7 — исходящая сферическая волна; formula_8 — угол рассеяния; formula_9 — амплитуда рассеяния.
