Using the results of a high mass resolution (256³ particles) N-body simulation of a cluster-forming region, we study the statistic σᵥ-M for low mass halos (M < 10¹² M), and we compare it with three theoretical models. At the final redshift halos are well described by the Truncated Isothermal Sphere model recently introduced by Shapiro, Iliev & Raga (1999). We speculate that this is a consequence of the action of tidal fields on galaxy formation within clusters.
