The photoelectron spectra of some 40 transition metal compounds have been measured using AlKα(1487 eV) and MgKα(1254 x-rays. included both simple salts (halides chalcogenides) hexacoordinated complexes (cyano- fluoro-) Cr(III), Mn(II, III), Fe(II, Co(III). From these data we determined the chemical shifts core electrons related results to a calculated charge based on Pauling's electronegativities. In addition, multiplet splitting has obtained for photoionization in 3s shell is discussed...

A double-focusing electrostatic electron spectrometer has been used to measure the K—LL Auger spectra resulting from impact for each of elements in gaseous molecules N2, O2, CO, NO, H2O, and CO2. An energy resolution 0.09% full width half-maximum was normally employed. method analyzing these complex is described. It involves identification normal satellite lines. The former are defined as arising single ionization K shell without additional excitation followed by an process which one fills...

Human object recognition is remarkably efficient. In recent years, significant advancements have been made in our understanding of how the brain represents visual objects and organizes them into categories. Recent studies using pattern analyses methods characterized a representational space human primate inferior temporal cortex which exemplars are discriminable cluster according to category (e.g., faces bodies). present study we examined structure representations emerges first 1000 ms...

Calculations of electron shake-off, based on the sudden approximation, have been made for several different processes. In particular, shake-off as result $\ensuremath{\beta}$ decay has computed each shells in 15 cases from an initial $Z=2 \mathrm{to} 92$. An interpolation results remaining elements. were with nonrelativistic Hartree-Fock wave functions lighter elements, and relativistic Hartree-Fock-Slater heavier ones. A comparison is available experimental data, satisfactory agreement...

An electron spectrometer which employs double focusing electrostatic plates is described. The photoelectron spectra obtained by bombarding methane, silane, germane, methyl fluoride, difluoromethane, and trifluoromethane with 21.22-eV photons are presented. experimental ionization energies compared theoretical other data, molecular-orbital assignments made for the energy values obtained. Broad maximum bands were observed in case of germane discussed terms Jahn–Teller distortion positive ions....

Increasing evidence suggests that attention can concurrently select multiple locations; yet it is not clear whether this ability relies on continuous allocation of to the different targets (a “parallel” strategy) or switches rapidly between periodic “sampling” strategy). Here, we propose a method distinguish these two alternatives. The human psychometric function for detection single target as its duration be used predict corresponding more attended targets. Importantly, predicted curves...

We effortlessly and seemingly instantaneously recognize thousands of objects, although we rarely—if ever—see the same image an object twice. The retinal can vary by context, size, viewpoint, illumination, location. present study examined how visual system abstracts category across variations in In three experiments, participants viewed images objects presented to different locations while brain activity was recorded using magnetoencephalography (MEG). A pattern classifier trained recover...
