Watson-Sommerfeld transformation Watson-Sommerfeld transformation[′wät·sən ′zȯm·ər‚felt i‚kwā·zhən] (mathematics) A procedure for transforming a series whose l th term is the product of the l th Legendre polynomial and a coefficient, al , having certain properties, into the sum of a contour integral of a (l) and terms involving poles of a (l), where a (l) is a meromorphic function such that a (l) equals al at integral values of l ; used in studying rainbows, propagation of radio waves around the earth, scattering from various potentials, and scattering of elementary particles. Also known as Sommerfeld-Watson transformation. Watt, James
Watt, James, Scottish engineer, 1736-1819. watt (W) - the SI unit of electrical power. |
