Cross sections and angular-distribution asymmetry parameters were measured directly for C(KVV) Auger electrons and C 1s photoelectrons from CO, CO/sub 2/, CF/sub 4/, and OCS, O(KVV) Auger electrons and O 1s photoelectrons from CO and CO/sub 2/, and S(LVV) Auger electrons and S 2p photoelectrons from OCS using synchrotron radiation. The measurements were made in the photon-energy ranges 270--350, 545--680, and 160--190 eV, respectively. Shape resonances were observed in all of these molecular systems. The cross-section results are compared with previous experimental data obtained by electron energy-loss measurements, electron--ion coincidence results, and photoabsorption studies. The asymmetry-parameter results are the first of their kind for these molecular core levels. The present results are compared with available theoretical predictions obtained from Stieltjes--Tchebycheff imaging techniques, Hartree-Fock static-exchange calculations, and the multiple-scattering method.
