Photoelectron spectroscopy of negative cobalt clusters: Correlation of promotion energy to reactivity
Photoelectron spectra of negatively charged cobalt clusters in the size range of 4-26 atoms have been obtained. The electron affinity (E.A.) values along with the reported ionization potential (I.P.) have been used to ...
Probing depths of low energy electrons in metals
Spin-polarized electron energy-loss spectroscopy has been used to investigate the probing depth of low energy ($\sim$30 eV) electrons in metals. A beam of spin-polarized electrons is directed at the surface of the sample ...
