The scattered atoms have a two-component angular distribution. One of the N components is very broad. In contrast, scattered Ar atoms exhibit only a sharp, single-component angular distribution. There are noteworthy features in the angle-resolved energy of the scattered N when compared with Ar.. Taking into account the relative masses involved, N atoms lose significantly more energy at the Surface than Ar.. However, there is a preferential loss mechanism that predominantly affects low-energy N atoms with small total scattering angle trajectories. The results are interpreted in terms of probing of different interaction potentials: strongly attractive and almost purely repulsive, and spin-state changes during the interaction of N with the surface appear probable.}, year = {2009}, journal = {Journal of Physical Chemistry A}, volume = {113}, number = {52}, pages = {15092-15099}, month = {Dec}, isbn = {1089-5639}, url = {://000273263700114 }, note = {ISI Document Delivery No.: 539OFTimes Cited: 0Cited Reference Count: 62}, language = {English}, }
