Study of the Scattering alpha Projectiles

摘要

The Method of Variational Moment Approach (VMA) depends on the relation that connects the real and imaginary parts of the optical model potential, known as the causality-based dispersion relation, where the Causality Principle sets forth that a scattered wave cannot be transmitted before the arrival of the incident wave. In this Study, an attempt is made to extend the application of the VMA Method, which dealt with simple systems, such as the proton- nucleus system and the neutron-nucleus system, in order to study the dispersion of complex systems such as the nucleus-nucleus system at a low range of energy.
