Abstract Polyelectrolytes are macromolecules which carry a large quantity of ionizable groups along their chains. By dissolving them in suitable solvents, for example water, these groups dissociate in highly charged macroions and an equivalent quantity of low-molecular counter ions. Through the connection between polymer and electrolyte properties this class of materials obtains its peculiar characteristic behaviour. The experiments undertaken here, were carried out using a commercial, anionic polyacrylamide with different hydrolysis factors in aqueous solutions. The reduced viscosity reaches a maximum which depends on the polymer concentration. The maximum also depends on the molar mass and is a function of the hydrolysis factor of the polymer.

Scattering Signal

We have taken angle-resolved data for the scattering of low-energy (<1 keV) 4 He + from deuterium adsorbed on a stepped Pd (331) surface. The impact geometry was "up the staircase," i.e. the 4 He + beam was perpendicular to and directly incident onto the unshadowed <011> Pd ledge atoms. A strong quasielastic scattering signal of 4 He + from D (4 He +/D) was observed at a forward-scattering angle of θ= 25° and an incidence angle of α= 76° from the (331) normal. The results agree with shadow-cone calculations of scattering first from Pd ledge atoms followed by a second event, 4 He +/D. The resultant adsorption geometry shows D to reside in the quasi-threefold ledge site on the surface directly above the bulk fcc octahedral void. These results are consistent with the previous 4 He + scattering study of the geometrically related Pd(110)-D(ads) system.
