Angular distribution coefficients for (γ, X) reactions with linearly polarized photons

The formalism for a linearly polarized γ-ray capture particle-out reaction is presented. The form given allows one to generate the expressions for the cross section as a function of the detected particle angle, θ, and the photon-polarization angle, φ, in terms of the reduced transition matrix elements. Tables, which allow the reader to construct these expressions, are presented for target spins and parities of 0+, 1 2+, 1+, and 3 2+; outgoing particle spins and parities of 0+, 1 2+, and 1+; residual nuclei spins and parities of 0+, 1 2±, 1+, and 3 2±; and multipolarities E1, M1, and E2. The tables are also labeled with equivalent Jπ combinations obtained by reversing the parities of any two of the three particles, which lead to the same expression for the cross section. © 1992.
