X-ray absorption measurements at the K-edge of silicon have been done in transmission mode on three powdered samples of porous silicon (p-Si) with 50%, 65% and 80% porosity, prepared by decreasing the HF content in the anodic solution. The analysis of EXAFS reveals a crystal-like structure of p-Si a
