We perform an extensive theoretical analysis of 10C nucleus with the use of various theoretical approaches involving the different nuclear potentials and different density distributions, as well as a simple cluster approach. We try to explain new measured and challenging experimental data on the 10C + 58Ni system at 35.3 MeV. First, we investigate the effect of thirteen different potentials. Then, we examine ten different types of density distributions for 10C nucleus. Finally, we present a simple calculation method for various cluster states of 10C, compare all the theoretical results with the experimental data, and obtain their improved agreement.
