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

We study the role of colliding geometry on the balance energy (Ebal) of mass-asymmetric systems by varying the mass asymmetry (η = AT - Ap/AT + AP, where AT and AP 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 Ebal of asymmetric systems. We find that, as we go from central collisions to peripheral ones, the effect of mass asymmetry on Ebal increases throughout the mass range. Interestingly, we find that for every fixed system mass (Atot) the effect of the impact parameter variation is almost uniform throughout the mass-asymmetry range. For each η, Ebal follows a power-law behavior (\propto Aτ) at all colliding geometries
