Contribution

It provides a detailed analysis of the impact of nuclear input ambiguities on reaction calculations at intermediate energies, highlighting their significance for reliable structure information.

Findings

Ambiguities significantly affect cross section calculations.

Careful nuclear input choices are essential for accurate spectroscopic factors.

Large uncertainties are present at 100 and 200 MeV energies.

Abstract

We investigate the impact of ambiguities coming from the choice of optical potentials and nucleon-nucleon scattering cross sections on the spectroscopic factors extracted from the $^{12}$C($p,2p$)$^{11}$B reaction. These ambiguities are evaluated by analyzing the cross sections of the $^{12}$C($p,2p$)$^{11}$B reaction at 100 and 200 MeV within the framework of the distorted-wave impulse approximation with realistic choices of nuclear inputs. The results show that the studied ambiguities are considerably large in this energy region and careful choices of nuclear inputs used in the reaction calculations are required to extract reliable structure information.
