“…The imaginary part comprises the volume term and complicated surface term, in which the minimum value (1.5 MeV) differs by 96% from the maximum value (37.67 MeV). The success story of the optical potential generated by theflexible Ginocchio potential [22][23][24] catalyzes us to explain elastic scattering data and threshold anomaly of the system. The formalism of Section 2 is applied to analyze the experimental data.…”

A new form of potential is used to treat the optical model unequivocally for the analysis of scattering results of the 58 Ni + 27 Al system. The phenomenological optical potential is formed with the Ginocchio potential for analysis near the Coulomb barrier. Theoretical calculations explain the experimental outcomes over a wide range of colliding energies, and hence exhibit threshold anomaly. An inbuilt non-trivial behaviour in the formulation near the Coulomb barrier position is found essential for a successful explanation of the experimental results.

The phenomenon of proton emission is treated as a process of asymmetric fission through a one-dimensional potential barrier developed due to combined effects of the Coulomb potential, centrifugal potential and various renormalization processes. The barrier is simulated to an asymmetric, smooth and analytically solvable potential with adjustable depth, shape and range. The half-lives of proton emitters in the mass range A = 105-171 have been calculated using exact expression for the transmission coefficients. Good agreement with the experimental data is obtained by the adjustment of just one parameter in all the cases.

“…Woods-Saxon (WS) potential, modified WS potential and Gaussian potential are few examples of phenomenological nuclear-potentials those are associated with the optical model analysis. In this paper we use Ginocchio potential to build an optical potential [19][20][21] for analysis purpose. The short-ranged Ginocchio potential is an analytically solvable asymmetric potential.…”

We use a phenomenological optical potential constructed in consideration of a versatile potential developed by Joseph N. Ginocchio. The optical potential uses less number of energy-dependent parameters to analyse nuclear scattering data. We study the ratios of elastic to Rutherford differential scattering cross sections of the system 6Li+90Zr at various energies, namely, 10.19, 11.11, 12.07, 13.95, 15.84, 17.71, 19.60, 23.36, 28.05 and 31.87 MeV in the centre-of-mass system. A study of angular distributions is performed in a wide angular range. Our theoretical calculations explain the experimental results and follow breakup threshold anomaly phenomenon near the Coulomb barrier. We discuss the variation of reflection function |Sl| with ‘l’ for each contributing partial wave and calculate reaction cross section for the system against the projectile energy 31.87 MeV with permissible error.
