Systematic investigation of the Cooper minimum for the hydrogen halides

Angle-resolved photoelectron spectroscopy has been carried out on the two outermost molecular orbitals of HBr using synchrotron radiation from a photon energy of 14 to 110 eV. Both partial cross sections σ and angular distribution parameters β have been determined experimentally. For comparison, cal...

Description
Summary:Angle-resolved photoelectron spectroscopy has been carried out on the two outermost molecular orbitals of HBr using synchrotron radiation from a photon energy of 14 to 110 eV. Both partial cross sections σ and angular distribution parameters β have been determined experimentally. For comparison, calculations were also carried out on σ and β using the multiple scattering Xα method. Both the experimental and calculated results are discussed in terms of the Cooper minimum. Comparison is made with earlier results on HCl and HI and with results on the rare gases, which are isoelectronic with the hydrogen halides.
