SUMMARY
The discussion clarifies the distinction between effective area and actual area in the context of the Total Collisional Cross-Section. The effective area is defined as the area normal to the direction of incidence that a target presents to an incoming projectile, influenced by the fields generated by the target. In contrast, the actual area refers to the physical space occupied by the target, such as approximately ten femtometers for a bare nucleus. Consequently, the effective area is larger than the actual area due to the influence of these fields on incoming projectiles.
