Theoretical modeling demonstrates accurate reaction cross sections in high-energy nucleus-nucleus collisions, highlighting the role of Coulomb dissociation in heavy-target scatterings.
A calculation of the complete Glauber amplitude is formulated with the use of an effective nucleon-target profile function. By relating the profile function to the elementary nucleon-nucleon profile function, a simple formula is derived to calculate the optical phase for nucleus-nucleus scattering. The resultant phase makes it possible to successfully reproduce much reaction cross section data at 800 MeV/nucleon. The effect of Coulomb dissociation on the optical phase is discussed. Its importance is studied in cases of the breakup of ⁶He and ⁹Li as well as the elastic scatterings of nuclei such as ¹²C and ⁶He by heavy targets.
