Role of colliding geometry on the balance energy of mass-asymmetric systems

We study the role of colliding geometry on the balance energy (E-bal) of mass-asymmetric systems by varying the mass asymmetry (eta = A(T) - A(p)/A(T) + A(P), where A(T) and A(P) are the masses of the target and projectile, respectively) from 0.1 to 0.7, over the mass range 40-240 and on the mass dependence of the balance energy. Our findings reveal that colliding geometry has a significant effect on the E-bal of asymmetric systems. We find that, as we go from central collisions to peripheral ones, the effect of mass asymmetry on E-bal increases throughout the mass range. Interestingly, we find that for every fixed system mass (A(tot)) the effect of the impact parameter variation is almost uniform throughout the mass-asymmetry range. For each eta, E-bal follows a power-law behavior (proportional to A(tau)) at all colliding geometries.
