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 J^π combinations obtained by reversing the parities of any two of the three particles, which lead to the same expression for the cross section. © 1992.
