Abstract: A structure analysis of the Si(111)2\textcopyright{}1 surface is performed using extensive new low-energy electron-diffraction data (12 beams) Although the $\ensuremath{\pi}$-bonded chain model in its original form shows gross disagreement with low-energy electron diffraction, a modification of that structure gives moderate agreement The major modifications are a buckling in the outer chain and an overall compression
