We report the results of an attempt to study the velocity structure of the
core of the cluster A2218 in order to probe its dynamical state. The aim is to
understand if the core is indeed virialized? relaxed? or in hydrodynamic
equilibrium? We use cluster lensing data in conjunction with the optical galaxy
data to solve in detail for the nature of galaxy orbits and the velocity
anisotropy in the core. We present our preliminary results below.Comment: uuencoded compressed postscript, without figure. The preprint is
