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 mass and decay of the ss member of the 1 3 F 4 meson nonet are investigated in the framework of the Regge phenomenology and the 3 P 0 model. We propose, based on the results, that the assignment of the ss member of the 1 3 F 4 meson nonet will require additional testing in the future. Our results also provide information for future studies of the 1 3 F 4 meson nonet.
