摘要：

We present the log(N)-log(S) diagram and an angular clustering analysis of point-like X-ray sources for the XMM-Newton Large Scale Structure (XMM-LSS) Survey. Though designed to study the properties and evolution of distant X-ray clusters up to z similar to 1, the large contiguous area planned for the full XMM-LSS survey is ideal for studying X-ray-selected AGN and their clustering properties. Our goal is to test the AGN unified scheme paradigm by studying the clustering of X-ray point-like sources. A clustering analysis of a 4.2 deg(2) contiguous region in the soft ([0.5-2] keV) and hard ([210] keV) energy bands is presented here. The angular correlation function and the nearest neighbour test have been performed in each band. Both tests only reveal a weak clustering in the soft X-ray band.
