Abstract
We have developed a time-of-flight detector system which improves the resolution of standard He+ forward recoil spectrometry (FRES) to better than 300 Å. The technique was used to determine the shape of the concentration profile at the surface of polymer blends of deuterated polystyrene (d-PS) and protonated polystyrene (PS). The results are discussed in terms of the predictions of mean field theories.
