Includes data on atoms, diatomic molecules, triatomic molecules, and polyatomic molecules.In other cases, the available data are presented graphically. Where the accuracy of the absolute partial cross sections is deemed sufficient (less than five percent), numerical tables are included in this new work. Thus, the determination of partial cross sections continues to be an active field, with more recent results in some cases superseding earlier ones. The newer light sources encouraged experimentalists to develop improved instrumentation. The newer devices have also extended the energy range of the light sources to include the K-shells of the species discussed here. A contrast, however, is that photoabsorption measurements, being of order I/Io, do not require the most intense light sources, whereas acquiring data on the products of light interactions with gaseous matter (ions, electrons, various coincidence measurements) has benefited significantly with the arrival of second- and third-generation synchrotrons. In this work Joseph Berkowitz selected the 'best' absolute partial cross sections for the same species as included in the companion work. For small kinetic energies, differences between experimental results and theoretical predictions are identified.Ītomic and Molecular Photoabsorption: Partial Cross Sections is a companion work to Joseph Berkowitzs earlier work, Atomic and Molecular Photoabsorption: Absolute Total Cross Sections, published with Academic Press in 2002. We also probe the influence of the Auger kinetic energy on the distortion of the photoline caused by the postcollision interaction effect. For the M4,5VV decay in HBr this propensity rule has to be supplemented by the requirement that the Auger-electron channel and the other valence orbital have the same preferential orientation. The branching ratios for the Br 3d−1 Auger decay to the 4p(σ,π)−2 with Σ symmetry follow the propensity rule of L2,3VV Auger decay stating that the oriented core holes decay preferentially by involving a valence electron from an orbital with the same spatial orientation. Experimental and theoretical data are in good agreement and conform to results for the 4pπ−2 final states from a previous analysis of the high-resolution conventional Auger-electron spectrum. The branching ratios for the Auger decay of the five different core-hole states to the 4p(σ,π)−2 dicationic final states are determined.
