IMPROVEMENTS TO THE RADIUS OF CONVERGENCE OF DIRECT INVERSION TECHNIQUES IN HELIUM ATOM SCATTERING

SHUTTLEWORTH, I. G. - In: Surface Review and Letters (SRL) 15 (2008) 05, pp. 519-523

Recent studies (I. G. Shuttleworth, Surf. Rev. Lett. 14(2) (2007) 321) have demonstrated a direct method of diffraction … pattern inversion for the helium atom scattering (HAS) experiment. The method requires the expansion of the Patterson function …

STUDIES OF THE ADSORPTION OF CYANOGEN (C2N2) ON Cu(001) USING HELIUM ATOM SCATTERING

SHUTTLEWORTH, I. G. - In: Surface Review and Letters (SRL) 14 (2007) 05, pp. 863-872

The adsorption of cyanogen (C2N2) on Cu(001) has been investigated using helium atom scattering. Adsorption at 263 K produces a two domain structure with periodicity c(10 × 6) and symmetry c2 mm. The principle axes of the two domains in the c(10 × 6) pattern lie at right angles to one another....

BENCHMARKING PATTERSON ANALYSIS IN HELIUM ATOM SCATTERING

SHUTTLEWORTH, IG. - In: Surface Review and Letters (SRL) 14 (2007) 01, pp. 1-4

The technique of Patterson analysis has proven to be a powerful tool in the deduction of structures, both in 2- and 3-D. Using the standard formulation of the Patterson function, the process has been benchmarked for the Helium Atom Scattering (HAS) experiment. Analytically expanding the...

STUDIES OF THE ADSORPTION OF ACETONITRILE (CH3CN) ON Cu(001) USING HELIUM ATOM SCATTERING

SHUTTLEWORTH, I. G. - In: Surface Review and Letters (SRL) 14 (2007) 03, pp. 387-394

The adsorption of acetonitrile (CH3CN) on Cu(001) has been studied using elastic Helium atom scattering (HAS) and has been analyzed using a novel method of direct HAS diffraction image inversion. At low temperatures (138 K) acetonitrile permanently adsorbs forming a c(4 × 2) structure at...
