Using the isospin dependent quantum molecular dynamics model, we study the effect of charge asymmetry and isospin dependent cross-section on d N/((cos 2 phi) and d N/p(t) d p(t) Simulations have been carried out for the reactions of X-124(m) + X-124(m), where in = (47.50 and 59) and S-40(16) + S-40(16). Our study shows that these parameters depend strongly on the isospin of cross-section and charge asymmetry. The distribution of free nucleons is symmetric but the distribution of nucleons constituting the light mass fragments, which are contributing in elliptical flow, is not symmetric around the beam axis.
