| 释义 | > as lemmasS-matrix 11. S-matrix (Physics): a scattering matrix, i.e. a matrix of probability amplitudes that occurs in the expression of the initial wave functions in a scattering process in terms of all the possible final wave functions. [After German matrix S (W. Heisenberg 1943, in Zeitschr. f. Physik CXX. 521).] ΘΚΠ the world > matter > physics > quantum theory > quantum mechanics > wave mechanics > [noun] > scattering matrix S-matrix1945 1945 C. Møller in Matematisk-Fysiske Meddelelser 23 i. 18 The discrete energy values are completely independent of the form of the S-matrix. 1964 W. K. Heisenberg in Cambr. Rev. 24 Oct. 47/1 The S-matrix elements for complicated processes will be functions of many variables. 1974 Nature 15 Mar. 265/1 He begins by developing the mathematical description starting from the Minkowski formalism of space-time, passing briefly through field theory, finally arriving at the S-matrix formalism which is to form the basis for the rest of the investigation. < as lemmas |
