Neutron emission from the photon-induced reactions in UPC of heavy ions - impact of new ALICE data

Key Points

• This research aims to calculate the cross section for neutron production in ultra-peripheral collisions of lead isotopes.
• Developed a model to analyze neutron production based on energy available in the thermalized phase.
• Compared model predictions with recent neutron measurements from ALICE.
• Examined the influence of multiple photon exchanges on neutron emission.
• The model successfully aligns with the recent ALICE data on neutron production.
• Illustrated the significant contribution of multiple photon exchanges to neutron emission.
• Highlighted that only a fraction of energy is utilized during the thermalized phase.
