Analysis of elastic α-nucleus scattering data at 240 MeV

Working within the framework of the Coulomb modified Glauber model we fit the elastic differential scattering cross section of 240 MeV {alpha} particle on {sup 58}Ni using the effective N-{alpha} amplitude with one adjustable parameter. It is found that once the effective amplitude is calibrated on {sup 58}Ni by varying the adjustable parameter, it very nicely reproduces the available elastic {alpha} scattering data on other nuclei at the same energy.
