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