We have studied the photoionization cross sections and photoelectron asymmetry parameters for all molecular orbitals of acetylene. These cross sections were obtained using accurate frozen-core Hartree-Fock continuum orbitals in the final-state wave function. The Hartree-Fock continuum equations were solved using the iterative Schwinger variational method. These fixed-nuclei cross sections are compared with available experimental data and with results obtained using the Stieltjes moment theory approach and the continuum multiple scattering method. The possible role of a shape resonance in the 1πu→kπg channel and the resonant structure of the σu continuum are discussed in some detail. © 1984 American Institute of Physics.
