Dm. Danailov et al., Multimodal angular distributions in grazing scattering of fast He-atoms from Fe(001) surfaces, NUCL INST B, 164, 2000, pp. 583-587
We measured angular distributions in grazing scattering of 10 keV He-0-atom
s incident along the [1 0 0] direction of an Fe(0 0 1) surface. Depending o
n the incidence angle different types of multimodal distributions are obser
ved. Classical molecular dynamics computer simulations relate the angular c
haracteristics to rainbow singularities and focusing effects. (C) 2000 Else
