Hydrogen chemisorption on ferromagnetic metals

The problem of hydrogen chemisorption on ferromagnetic substrates is studied using the Anderson-Newns Hamiltonian with the explicit inclusion of the substrate magnetization. A model density of states is used to approximate the particular case of nickel. A polarized solution is obtained for the adatom, which can also explain the rather large width of the photoemission peak observed for hydrogen chemisorbed on nickel.
