Photoelectron asymmetry parameters (β) and partial photoionization cross-sections have been measured for ionization from the molecular orbitals of CH3F and CH3Cl using synchrotron radiation in the photon energy range 19 to 115 eV. Cooper minima are observed in the β spectra of CH3C1 for ionization from orbitals with Cl 3p character. Several shake-up bands observed in the F 2s and Cl 38 ionization energy region indicate a breakdown of the one-electron picture of ionization. The position and relative intensities of the satellite bands are compared with the results of Green's function calculations.
