Description | ||||||
The transmission probabilities through the Coulomb barrier for reactions having difference barrier curvatures have been calculated. We have chosen three heavy-ion fusion reactions with a fixed projectile and three targets in different mass region, namely, 16O+12C, 16O+58Ni, 16O+154Sm systems. The transmission probability for each system is evaluated by using parabolic approximation of potential barrier. It is found that the variation of transmission probability depends on the different curvature of Coulomb barriers of colliding systems. For lighter systems, the transmission probability is closer to that of classical result. As the system becomes heavier, the curvature of the barrier becomes larger and consequently the deviation from the classical limit becomes significant. Thus, the quantum effect in transmission probability is found to be larger in heavy-ion fusion reactions with heavy target than those of lighter ones. | ||||||
