On the Calculation of Invariant Tensors in Gauge Theories

Abstract

In this study, the 6 Li( 3 He,d) 7 Be transfer reaction at 33.3 and 34 MeV is analyzed in the framework of the optical model by using the FRESCO code based on the distorted wave Born approximation (DWBA) method for temperature-dependent and temperature-independent density distributions, different nuclear potentials, and different nucleon-nucleon interactions. The nuclear potential is assumed to have real and imaginary parts in the entrance and exit channels together with the Coulomb potential. The similarities and differences of all the different approaches are discussed, and alternative density, alternative nuclear potential, and alternative nucleonnucleon interactions are suggested.
